drm/i915/mtl: avoid stringop-overflow warning
The newly added memset() causes a warning for some reason I could not
figure out:
In file included from arch/x86/include/asm/string.h:3,
from drivers/gpu/drm/i915/gt/intel_rc6.c:6:
In function 'rc6_res_reg_init',
inlined from 'intel_rc6_init' at drivers/gpu/drm/i915/gt/intel_rc6.c:610:2:
arch/x86/include/asm/string_32.h:195:29: error: '__builtin_memset' writing 16 bytes into a region of size 0 overflows the destination [-Werror=stringop-overflow=]
195 | #define memset(s, c, count) __builtin_memset(s, c, count)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/i915/gt/intel_rc6.c:584:9: note: in expansion of macro 'memset'
584 | memset(rc6->res_reg, INVALID_MMIO_REG.reg, sizeof(rc6->res_reg));
| ^~~~~~
In function 'intel_rc6_init':
Change it to an normal initializer and an added memcpy() that does not have
this problem.
