Julius Werner 7476b4bd0e tegra124: Save SDRAM parameters to PMC registers for LP0 
This patch ports the code to save SDRAM parameters into PMC scratch
registers (for use by the BootROM on LP0 resume) from U-Boot. The
original "translation table" mechanism stays pretty much unchanged for
now, just simplified a few things and adapted it to our code flow. Gets
called unconditionally from the end of sdram_init() (which means we
won't support this for static BCT-style memory initialization).

BUG=chrome-os-partner:25062
TEST=Installed AVP LP0 handler blob that Dylan pulled out of U-Boot in
/lib/firmware/tegra12x/tegra_lp0_resume.fw. Confirmed that I can LP0
suspend/resume. Also compared PMC register dumps with a U-Boot system
and confirmed that there were no unexpected differences.
