[PULL,07/26] KVM: arm/arm64: Rename soft timer to bg_timer

Commit Message

From: Christoffer Dall <[e-mail]>

As we are about to introduce a separate hrtimer for the physical timer,
call this timer bg_timer, because we refer to this timer as the
background timer in the code and comments elsewhere.
