mtd: maps: physmap-core: fix flash size larger than 32-bit
mtd-ram can potentially be larger than 4GB. get_bitmask_order() uses
fls() that is not guaranteed to work with values larger than 32-bit.
Specifically on aarch64 fls() returns 0 when all 32 LSB bits are clear.
Use fls64() instead.
Fixes: ba32ce95cbd987 ("mtd: maps: Merge gpio-addr-flash.c into physmap-core.c")
