armv8: aarch64: Fix the warning about x1-x3 nonzero issue
For 64-bit kernel, there is a warning about x1-x3 nonzero in violation of boot protocol. To fix this issue, input argument 4 is added for armv8_switch_to_el2 and armv8_switch_to_el1. The input argument 4 will be set to the right value, such as zero.
