CONFIG_SPL_SERIAL_SUPPORT had already been migrated to Kconfig, but
existed in some include files; fix those up here.

SYS_ARCH_TIMER guards the usage of the ARM Generic Timer (aka arch
timer) in U-Boot.
At the moment it is mandatory for ARMv8 and used by a few ARMv7 boards.
Add a proper Kconfig symbol to express this dependency properly,
allowing certain board configuration to later disable arch timer in case
there are any problems with it.

After commit 46fc679ede5f69 ("arm: timer: get frequency for arch timer
armv7 in cp15 cntfrq") the ARM architected timer driver knows how to
determine the timer frequency at runtime by reading the CNTFRQ register,
so we don't need to hardcode the timer frequency anymore.

These symbols are declared in Kconfig, so it's wrong to set them in
header files.

Note that this is not size-neutral - some 'default y' options will now
get turned on by Kconfig, such as CONFIG_CMD_DM=y and CONFIG_DM_STDIO=y.

We have not had CONFIG_NET_MULTI be meaningful for quite some time, drop

This converts the following to Kconfig:
   CONFIG_SPI

This partly involves updating code that assumes that CONFIG_SPI implies
things that are specific to the MPC8xx SPI driver.  For now, just update
the CONFIG tests.  This also involves reworking the default for
CONFIG_SYS_DEF_EEPROM_ADDR so that we don't set it when we cannot make a
reasonable default, as it does not cause any compile failures.

This allows using the full SPL framework on mxs devices.  In this
mode, the u-boot.sb image loaded by the boot ROM contains only the
SPL which then loads U-Boot proper or a kernel in falcon mode.
