Refreshed all patches.
Altered patches:
- 220-optimize_inlining.patch
- 816-pcie-support-layerscape.patch
This patch also restores the initial implementation
of the ath79 perfcount IRQ issue. (78ee6b1a40b5)
It was wrongfully backported upstream initially and got reverted now.

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%
kernel size with CONFIG_OPTIMIZE_INLINING=n

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

Optimized inlining was disabled by default when gcc 4 was still
relatively new. By now, all gcc versions handle this well and there
seems to be no real reason to keep it x86-only.
