[U-Boot] [PATCH v3 12/57] ram: rk3399: Rename sys_reg with sys_reg2

[Jagan Teki]

Use dram config variable name as sys_reg2 instead of sys_reg
since the final variable value is to written into a pmugrf
register named as sys_reg2.

This reflect the both variable and associated register
names are same and also help to add next sys_reg's to
add it in future.
