[PATCH] drivers: hab: work-around GCC -Wmaybe-uninitialized false-positive

[Ahmad Fatoum]

imx_hab_read_srk_hash() always initializes the buffer that's passed in
fully. Yet, gcc-13.1.1 warns that this is not always the case, but
inlining imx_hab_read_srk_hash() makes the false-positive warning disappear.
Pacify GCC by just zero-initializing the 256-bit srk buffer.
