arm64: Silence clang warning on mismatched value/register sizes
[ Upstream commit:5.4-rM2-2.2.x-imx-squashed27a22fbdee
] Clang reports a warning on the __tlbi(aside1is, 0) macro expansion since the value size does not match the register size specified in the inline asm. Construct the ASID value using the __TLBI_VADDR() macro. Fixes:222fc0c850
