only if boot_status == 7

but since BOOT_STATUS is REG_GENMASK(3, 1) I assume that there
might be other values, beyond currently documented 4 & 7

so even if we print "Other" there will be still numerical
value "(7)" or "(1)" that could be used for debug/triage

but I can add helper

	static const char *boot_status_str(u8 boot_status)

to return friendly name for all currently known codes
(and "Other" or NULL for unknown codes)
