Remove EL2/EL1 GICv3 register updates

From Linux 3.17 onwards, the mainline kernel has support for GICv3
systems and if EL3 exists, it only needs to initialise ICC_SRE_EL3.SRE
and ICC_SRE_EL3.Enable to 1. Hence, this patch removes the redundant
updates of ICC_SRE_EL2 and ICC_PMR_EL1.

NOTE: For partner software's which enter kernel in EL1,
ICC_SRE_EL2.Enable and ICC_SRE_EL2.SRE bit needs to be set to 1
in EL2 before jumping to linux.
