Marc Zyngier 4e9bfe6969 clocksource/drivers/arm_arch_timer_mmio: Add MMIO clocksource 
The MMIO driver can also double as a clocksource, something that was
missing in its previous incarnation. Add it for completeness.

Marc Zyngier 4891f01527 clocksource/drivers/arm_arch_timer: Add standalone MMIO driver 
Add a new driver for the MMIO side of the ARM architected timer.
Most of it has been lifted from the existing arch timer code,
massaged, and finally rewritten.

It supports both DT and ACPI as firmware descriptions.
