drivers/intel/fsp1_1/cache_as_ram.S: Use _car_stack area for stack

Top of Temp RAM is used as bootloader stack, which is the
_car_region_end area. This area is not equal to CAR stack area as
defined in car.ld file.

Use _ecar_stack (end of CAR stack) as starting stack location.

Tested VBOOT, Vendorboot security and no security on Facebook FBG1701.
