linux-gen: wait_until: add generic 8-bit wait until function
Add architecture independent 8-bit wait until function. The ARM specific
WFE loop is temporarily removed from scalable scheduler implementation. WFE
support will be added back in a following commit, which adds aarch64
specific wait until functions.
