Add the clock support.

Add support for clocks needed by MACs to ast2500 clock driver.
The clocks are D2-PLL, which is used by both MACs and PCLK_MAC1 and
PCLK_MAC2 for MAC1 and MAC2 respectively.
The rate of D2-PLL is hardcoded to 250MHz -- the value used in Aspeed
SDK. It is not entirely clear from the datasheet how this clock is used
by MACs, so not clear if the rate would ever need to be different. So,
for now, hardcoding it is probably safer.
The rate of PCLK_MAC{1,2} is chosen based on MAC speed selected through
hardware strapping.
So, the network driver would only need to enable these clocks, no need
to configure the rate.

This driver uses Generic Pinctrl framework and is compatible with
the Linux driver for ast2500: it uses the same device tree
configuration.
Not all pins are supported by the driver at the moment, so it actually
compatible with ast2400. In general, however, there are differences that
in the future would be easier to maintain separately.

This change switches all existing users of ast2500 Watchdog to Driver
Model based Watchdog driver.
To perform system reset Sysreset Driver uses first Watchdog device found
via uclass_first_device call. Since the system is going to be reset
anyway it does not make much difference which watchdog is used.
Instead of using Watchdog to reset itself, SDRAM driver now uses Reset
driver to do that.
These were the only users of the old Watchdog API, so that API is
removed.
This all is done in one change to avoid having to maintain dual API for
watchdog in between.

Add Reset Driver for ast2500 SoC. This driver uses Watchdog Timer to
perform resets and thus depends on it. The actual Watchdog device used
needs to be configured in Device Tree using "aspeed,wdt" property, which
must be WDT phandle, for example:
rst: reset-controller {
compatible = "aspeed,ast2500-reset";
aspeed,wdt = <&wdt1>;

A weak version of the function board_usb_init is implemented in:
common/usb.c
drivers/usb/host/xhci-omap.c
To fix the double implementations:
* Convert the board_usb_init function in drivers/usb/host/xhci-omap.c
normal (not weak).
* The function board_usb_init in drivers/usb/host/xhci-omap.c calls to
the weak function omap_xhci_board_usb_init.
* Rename board version of the function board_usb_init to
omap_xhci_board_usb_init.
Done only for boards that defines CONFIG_USB_XHCI_OMAP.
To achieve the same flexibility with the function board_usb_cleanup:
* Add a normal (not weak) implementation of the function
board_usb_cleanup in drivers/usb/host/xhci-omap.c
* The function board_usb_cleanup in drivers/usb/host/xhci-omap.c calls
to the weak function omap_xhci_board_usb_cleanup.

This commit adds support for DM I2C on sunxi platform. It can coexist
with old style sunxi I2C driver, because it is still used in SPL and
by some SoCs.
Because sunxi platform doesn't yet support DM clk, reset and pinctrl
driver, workaround is needed to enable clocks and set resets and
pinctrls. This is done by calling i2c_init_board() in board_init().
This means that CONFIG_I2Cx_ENABLE options needs to be correctly set
in order to use needed I2C controller.

This originally started out as
"pinctrl: Kconfig: reorder to keep Rockchip options together"
and tried to keep the Rockchip-related config options together.
However, we now rewrite all chip-specific driver selections to start
with CONFIG_PINCTRL_ (with the inadvertent changes to related
Makefiles) and sort those alphabetically. And as this already means
touching most of the file, we also reformat the help text to not exceed
80 characters (but make full use of those 80 characters).
