x86: sizeof-array-div error in lpc_common_early_init

Building qemu-x86_64_defconfig with GCC 11.0 fails with:

arch/x86/cpu/intel_common/lpc.c:
In function ‘lpc_common_early_init’:
arch/x86/cpu/intel_common/lpc.c:56:40:
error: expression does not compute the number of elements in this array;
element type is ‘struct reg_info’, not ‘u32’ {aka ‘unsigned int’}

arch/x86/cpu/intel_common/lpc.c:56:40: note: add parentheses around the
second ‘sizeof’ to silence this warning

Add parentheses to silence warning.
