fix 'array subscript 0 is outside array bounds' for newer gcc versions

[gibbz00]

I'm got the following error when building:

lib/sdk11/components/libraries/bootloader_dfu/bootloader_settings.c: In function 'bootloader_mbr_addrs_populate': lib/sdk11/components/libraries/bootloader_dfu/bootloader_settings.c:45:7: error: array subscript 0 is outside array bounds of 'const uint 32_t[0]' {aka 'const long unsigned int[]'} [-Werror=array-bounds] 45 | if (*(const uint32_t *)MBR_BOOTLOADER_ADDR == 0xFFFFFFFF) compilation terminated due to -Wfatal-errors. cc1: all warnings being treated as errors make: *** [Makefile:393: _build/build-feather_nrf52840_express/bootloader_settings.o] Error 1

Looked around and found this issue over at QMK: qmk/qmk_firmware#17064
The main bug referenced can be found here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105523

In essence: gcc versions of 12 and above have a regression bug that can be solved by adding the compile flag --param=min-pagesize=0. The surrounding conditional in the commit checks that the flag is supported. (Small adaptations to QMKs fix really; qmk/qmk_firmware@2160810)

Anyway, building works well for me with this minor change.

thank you for the fix. Indeed I have encountered some issue with gcc throwing incorrect warning lately.

This problem appeared again on gcc13, and only gcc12 was judged in the code.
