On keystone2 Lamarr and Edison platforms, the PA clocksource
mux in PLL REG1, can be changed only after enabling its clock
domain.
So selecting the output of PASS PLL as input to PA only after
enabling the clockdomain.
This is as per the debug done by "Vitaly Andrianov <vitalya@ti.com>"
and based on the previous work done by "Hao Zhang <hzhang@ti.com>"

MLO(NAND/MMC boot image), is used for all the ks2 platforms.
Enabling it in config.mk so that these images will be automatically
built upon calling make. u-boot-spi.gph is already the build target,
so not including here.

NAND boot mode, ROM expects an image with a gp header in the
beginning and an 8bytes filled with zeros at the end. The same is
true for SD boot on K2G platforms but the file name should be MLO.
Renaming u-boot-nand.gph to MLO, so that same image can be used for
NAND and SD boots. And also not including all the u-boot only images
under CONFIG_SPL_BUILD.

Keystone has build rules introduced by commit ef509b9063 ("k2hk: add
support for k2hk SOC and EVM") and commit 0e7f2dbac6 ("keystone: add
support for NAND gpheader image").
These are not reused by other platforms for the build, hence there is no
clear benefit is maintaining them in the generic makefile as a build
target. move these to the keystone specific make option

There are two types of PLL for all keystone platforms:
Main PLL, Secondary PLL. Instead of duplicating the same definition
for each secondary PLL, have a common function which does
initialization for both PLLs. And also add proper register
definitions.
