The new 32bit DDR controller for TI's am62a family of SoCs shares much
of the same functionality with the existing 16bit (am64) and 32bit
(j721e) controllers, so this patch reorganizes the existing
auto-generated macros for the 16bit and 32bit controllers to make room
for the macros for the am62a's controller
This patch consists mostly of header/macro renames and additions with a
new Kconfig option (K3_AM62A_DDRSS) allowing us to select these new
macros during compilation.

The condition "~data" in the if-statement is a typo. The original
intention is to poll if SDRAM_PHYCTRL0_INIT bit equals to 0. So use
"data == 0" for instead.
Besides, the bit[1] of "phy_status" register is hardwired to
SDRAM_PHYCTRL0_INIT (with inverse logic). Since SDRAM_PHYCTRL0_INIT has
already done, remove the unnecessary checking of phy_status[1].

Currently the default initialisation frequency is 50MHz. Although
this does appear to be suitable for some LPDDR4 RAM chips, training at
this low frequency has been seen to cause Column errors, leading to
Capacity check errors on others.
Here we force RAM initialisation to happen at 400MHz before ramping up
to the final value running value of 800MHz after everything has been
successfully configured.
