Patch 1 switches AM64 to use GTC as system timer at A53 SPL/U-boot stage as done in other TI K3 platforms
Minor nuance clarification: We don't use System timer (aka GTC) directly. System timer[1] feeds the armv8 per cpu timer[2] - and the per-cpu timer is what we use.
Will be good to fixup the commit messages and $subject accordingly.
Patch 2 corrects DM timer freq to be 200MHz (used at R5 SPL stage)
