Add support for debug output very early during boot using the DEBUG_UART
mechanism. This uses a static fixed UART port configuration selected via
Kconfig options and dedicated print functions from debug_uart.h. This is
useful e.g. when debugging problems so early during boot, that not even
the DM is initialized at that point, and thus DM_SERIAL is not available
either.
This functionality is disabled by default. To activate it, define the
following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/
CFG_HSCIF/<nothing for regular SCIF>:
CONFIG_DEBUG_UART=y
CONFIG_DEBUG_UART_SCIF=y
CONFIG_DEBUG_UART_BASE=0xe6540000
CONFIG_DEBUG_UART_CLOCK=24000000
The later two options define the SCIF physical base address and SCIF
input clock in Hz. Optionally, to validate DEBUG_UART works, enable
the following as well to get early serial output message by default:
CONFIG_DEBUG_UART_ANNOUNCE=y

Both CONFIG_SCI and CONFIG_SCIF_USE_EXT_CLK options do not have a
matching Kconfig entry because they are internal to the SCIF driver.
Change their prefix to CFG_, i.e. CFG_SCIF_USE_EXT_CLK and CFG_SCI,
to reflect that and avoid interferring with Kconfig symbols. Since
neither of those options are defined elsewhere, no functional change.

Instead of waiting for empty FIFO condition before writing a
character, wait for non-full FIFO condition.
This helps in saving several tens of milliseconds during boot
(depending verbosity).

The u-boot console may show some corrupted characters when
printing in board_init() due to reset or baudrate change
of the UART (probe) before the TX FIFO has been completely
drained.
To fix this issue, and in case UART is still running, we now
try to flush the FIFO before proceeding to UART reinitialization.
For this we're waiting for Transmitter Complete bit, indicating
that the FIFO and the shift register are empty.
flushing has a 4ms timeout guard, which is normally more than
enough to consume the FIFO @ low baudrate (9600bps).

At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks. Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

At this point in the conversion there should be no need to have logic to
disable some symbol during the SPL build as all symbols should have an
SPL counterpart.
The main real changes done here are that we now must make proper use of
CONFIG_IS_ENABLED(DM_SERIAL) rather than many of the odd tricks we
developed prior to CONFIG_IS_ENABLED() being available.

There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.
Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.
Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.
Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.

The baud clock on some platform may change due to assigned-clock-parent
set in DT. In current flow the baud clock is only retrieved during probe
stage. If the parent of the source clock changes after probe stage, the
setbrg will set wrong baudrate.
To get the right clock rate, this patch records the baud clk struct to the
driver's priv, and changes the driver's flow to get the clock rate before
calling _mtk_serial_setbrg().

(as observable on a connected 'scope) to actually make it into the

the reference manual is not overly clear about this, and only
mentiones that "UCR3_RXDMUXSEL should always be set." - and since the
CR3 register reverts to its reset values after setting the baudrate,
setting this bit is done during '_mxc_serial_setbgr'

Commit d293759d55cc ("serial: ns16550: Add support for
SPL_DEBUG_UART_BASE") fixed support for setting correct early debug UART
base address in SPL.
But after this commit, output from Marvell A385 BootROM is truncated or
lost and not fully present on serial console.
Debugging this issue showed that BootROM just put bytes into UART HW output
buffer and does not wait until UART HW transmit all characters. U-Boot
ns16550 early debug is initialized very early and during its initialization
is resetting UART HW and flushing remaining transmit buffer (which still
contains BootROM output).
Fix this issue by waiting in init function prior resetting UART HW until
TxEmpty bit in UART Line Status Register is set. TxEmpty is set when all
remaining bytes from HW buffer are transmitted.
