mb/qemu-{i440fx,q35}: reduce default ROM size to 8M

QEMU doesn't allow to use bigger images with '-drive if=pflash', which
is required to make use of writable flash introduced in CB:82555. This
changes both default size in Kconfig as well as FMAP layouts.

Error thrown by QEMU when trying to use too big ROM:

qemu-system-x86_64: combined size of system firmware exceeds 8388608 bytes
