[PATCH v2 4/4] scripts/checkstack.pl: fix arm sp regex

From: Maninder Singh
Date: Fri May 08 2020 - 07:10:34 EST


if objdump has below entries;
c01ed608 <X>:
c01ed614: e24ddff7 sub sp, sp, #120 ; 0x78

c01f0d50 <Y>:
c01f0d50: e24dd094 sub sp, sp, #140 ; 0x8c

scripts fails to read stack usage.
so making regex $re for ARM similar to aarch64
