[PULL 19/19] KVM: arm/arm64: Fix broken GICH_ELRSR big endian conversion

[Christoffer Dall <cdall@kernel.org>]

From: Christoffer Dall <christoffer.dall@linaro.org>

We are incorrectly rearranging 32-bit words inside a 64-bit typed value
for big endian systems, which would result in never marking a virtual
interrupt as inactive on big endian systems (assuming 32 or fewer LRs on
the hardware).  Fix this by not doing any word order manipulation for
the typed values.
