arm64: kvm: use inner-shareable barriers for inner-shareable maintenance
commit ee9e101c11478680d579bd20bb38a4d3e2514fe3 upstream.
In order to ensure completion of inner-shareable maintenance instructions
(cache and TLB) on AArch64, we can use the -ish suffix to the dsb
instruction.
This patch relaxes our dsb sy instructions to dsb ish where possible.
