core/cortex-m0: Fix assembly
When compiling with clang, the following error is reported:
core/cortex-m0/switch.S:107:12: error: unknown token in expression
ldr r0, =#0xe000ed04 @ load 0xe000ed04's address
^
This change fixes the syntax, which generates the identical output
before and after the change:
/opt/coreboot-sdk/bin/arm-eabi-objdump -d
build/servo_micro/RW/core/cortex-m0/switch.o
0000006a <pendsv_handler>:
6a: b508 push {r3, lr}
6c: 4807 ldr r0, [pc, #28] ; (8c <pendsv_handler+0x22>)
BRANCH=none
BUG=b:172020503
