kernel: only optimized for size if small_flash
Add a new config option to allow to select the default compile optimization level for the kernel. Select the optimization for size by default if the small_flash feature is set. Otherwise "Optimize for performance" is set. Add the small_flash feature flag to all (sub)targets which had the optimization for size in their default kernel config. Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new setting. Exceptions to the above are: - lantiq, where the optimization for size is only required for the xway_legacy subtarget but was set for the whole target - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have plenty of space and an optimization for size doesn't make much sense - rb532, which has 128MByte flash Signed-off-by: Mathias Kresin <dev@kresin.me>
