Vinod G ac98827c9d gpu: nvgpu: Add L2 register read-backs following writes ...

LTC register write is followed by a register read
and if data doesn't match code will report the error.

Renamed existing nvgpu_writel_check function as
nvgpu_writel_loop as it loops until the write get success.

nvgpu_writel_check function write and read back and
compare the data.
