kernel: Activate CONFIG_OPTIMIZE_INLINING
This will reduce the size of the kernel if CONFIG_CC_OPTIMIZE_FOR_SIZE is
set like for all targets with small_flash feature flag.
I haven't seen any changes for an ARM64 target which optimizes the
kernel for speed instead.
On the ath79/tiny target the uncompressed kernel size was reduced by
3.2% and the compressed kernel size by 2.1%

This change is currently pending for kernel 5.2 and already in
linux-next, this updates our patch to match the upstream version.
