Sascha Bischoff 1017911fcc irqchip/gic-v5: Preserve ICC_CR0_EL1 state

In addition to EN, ICC_CR0_EL1 contains other fields, such as LINK and
LINK_IDLE. The driver only needs to modify EN, and must preserve the
values of all other fields when enabling or disabling the CPU
interface.

Define the missing LINK and LINK_IDLE fields, and use read-modify-write
accesses to update EN without affecting the rest of ICC_CR0_EL1.
