msm: kgsl: Remove some CP registers from snapshot dump

Do not dump CP_ME_STATUS and CP_ME_RAM_DATA from snapshot
register section. CP_ME_STATUS is an indexed register, should
not be part of register section, we already dump this register
in indexed register section. CP_ME_RAM_DATA is used to read data
present at RAM location address specified by CP_ME_RAM_RADDR,
this also should not be part of register section.
