zipl: Disable array-bounds warning

Browse Source 
Since GCC12 several warnings like the following are produced in
zipl/boot compile targets:

CC      zipl/boot/stage2.o
stage2.c: In function ‘start’:
stage2.c:99:24: warning: array subscript 0 is outside array bounds of ‘struct stage2_descr[0]’ [-Warray-bounds]
   99 |         stage2_descr = *(struct stage2_descr*)STAGE2_DESC;

This is the same issue as reported for the Kernel [1][2]. There is
currently no sane fix available, therefore simply disable the warning
for the zipl/boot/ targets.
