[Linaro-acpi] [PATCH part3 01/13] Remove unnecessary ldr from boot wrapper

From: Mark Rutland mark.rutland@arm.com

We currently do an ldr from GICC_CTLR to w0, then immediately overwrite w0 with a mov. Reading the GICC_CTLR has no effect on the state of the GIC, so there's no reason to do the ldr. It's also inconsistent with the way we set the GICD_CTLR.

Fix this.
