[PATCH] ARM: defconfig: Add IOSCHED_BFQ to the default configs

ARM systems are often memory constrained and more often than not
use slow single-channel storage such as flash memory or MMC/SD-cards.
For any interactive systems (such as mobile phones, tablets,
chromebooks...) the BFQ I/O scheduler will be desireable.

Make sure the BFQ I/O scheduler is available on these systems.

Loongarch, MIPS, m68k, UM and S390 has also enabled BFQ in their
defconfigs, cf commit b495dfed706c4c5873c0dab8930ad6eb1d276a6c
"um: Cleanup CONFIG_IOSCHED_CFQ" where the motivation is that
it replaces the former CFQ scheduler.
