Subject[PATCH] irqchip/gic-v3: Remove the unused register definition
Date
As per the GICv3 specification, GIC{D,R}_SEIR are not assigned and the
locations (0x0068) are actually Reserved. GICR_MOV{LPI,ALL}R are two IMP
DEF registers and might be defined by some specific micro-architecture,
Linux doesn't use them.

As they're not used anywhere in the kernel, just drop all of them.

Compile tested on top of mainline.
