[PATCH 00/38] irqchip: mips-gic: Cleanup & optimisation

This series cleans up the MIPS Global Interrupt Controller (GIC) driver
somewhat. It moves us towards using a header in a similar vein to the
ones we have for the MIPS Coherence Manager (CM) & Cluster Power
Controller (CPC) which allows us to access the GIC outside of the
irqchip driver - something beneficial already for the clocksource &
clock event driver, and which will be beneficial for further drivers
(eg. one for the GIC watchdog timer) and for multi-cluster work. Using
this header is also beneficial for consistency & code-sharing.

In addition to cleanups the series also optimises the driver in various
ways, including by using a per-CPU variable for pcpu_masks & removing
the need to read the GIC_SH_MASK_* registers when decoding interrupts in
gic_handle_shared_int().

This series requires my "[PATCH 00/19] MIPS: Initial multi-cluster
support" series to be applied first.
