MIPS: Malta: Enable BLK_DEV_INITRD
This configuration is useful for boot testing malta_defconfig in QEMU
with just a simple cpio initrd, instead of a full ext4 rootfs.
This results in an increase of ~164KB of vmlinux (with GCC 11.2.0):
$ diskus vmlinux.before
11.19 MB (11,194,368 bytes)
$ diskus vmlinux.after
11.36 MB (11,358,208 bytes)
This size increase comes from the fact that usr/Kconfig is sourced when
CONFIG_BLK_DEV_INITRD is enabled, which defaults to supporting several
decompression algorithms for compressed initrds. This seems like a
reasonable tradeoff but these configurations could be disabled in the
future if there are complaints about the size increase.
