[PATCH RESEND 09/16] sysreset: qcom-pshold: offset support

[Sam Day via B4 Relay]

From: Sam Day <me at samcday.com>

On older SoCs (such as MSM8960/MSM8930), PS_HOLD is exposed through
the TLMM aperture. To prepare for that use-case, this driver is updated
to accept arbitrary offsets from regbase.
