relevant bits for plld and to preserve the other two divider values
present in the upper 16 bits, otherwise they will always get set to zero
when programming plld.

data lacks the infrastructure to pass in divider flags.
Update the driver and data to account for these divider flags.

s does NOT actually enable ECC for the any platform
due to the multi second boot time increase that comes from the ECC
priming that is done as part of ECC init, but it can be enabled by
adding the 'ti,ecc-enable` property to the memorycontroller node in
k3-am642-r5-evm DT.

Use the appropriate fdtdec_setup_mem_size_base and
fdtdec_setup_bank_size calls in dram_init and dram_bank_init to pull
these values from DT, where they are already available, instead of
hardcoding them.

Call into k3-ddrss driver to fixup device tree and resize the available
amount of DDR if ECC is enabled.
A second fixup is required from A53 SPL to take the fixup as done from
R5 SPL and apply it to DT passed to A53 U-boot, which in turn passes
this to the OS.

The current address being read from dt actually represents the ddrss_ctl
memory region, while ddrss_ss region is something else. Introduce
ddrss_ctl_regs and use it to free up ddrss_ss_regs for its proper
purpose later so that we can avoid confusion.
