Code Issues

kernel: further clean-up options and defaults 

Remove `if !SMALL_FLASH` in places which are anyway already augmented
by `if !SMALL_FLASH`.
Always enable CONFIG_BLK_DEV_THROTTLING on !SMALL_FLASH devices rather
than just enabling it on bcm27xx.
Enabled CPU bandwidth provisioning for FAIR_GROUP_SCHED on !SMALL_FLASH
devices as CONFIG_FAIR_GROUP_SCHED is already enabled and becomes more
useful for cgroups with that option enbled as well.
