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

These options are handled by generic configuration
Targets that need these options should select KERNEL_DEVMEM
and/or KERNEL_DEVKMEM options on OpenWRT's config

Updated pfe kernel patch to clean up iounmap(pfe->ddr_baseaddr).

Some layerscape devices (ls1012ardb/ls1012afrdm/ls1046ardb/ls1088ardb)

This patch is to drop using ext4 rootfs and use ubifs rootfs instead
which is more proper for SPI-NOR flash.

Disable CONFIG_PROC_PAGE_MONITOR in most places and only keep it enabled
for virtual targets such as malta or potent ones like x86.
This saves up to 4KB of uncompressed kernel size and significantly
decreases CPU load under certain workloads.

While bumping 4.14, the kernel build failed due to missing CONFIG_KASAN

It was only added in 4.0, so not needed in config-3.18.

A previous patch disaggregated kernel patch 601 intending to
reverse the ndo_get_stats64 change, but it also dropped
many other changes without a reason. This caused build issue
for layerscape. This patch is to fix that with below steps.
1. Reversed patch "1c4415a layerscape: reverse changes to ndo_get_stats64",
but kept kernel patch 701 which was a proper fix.
2. Reversed the ndo_get_stats64 change in kernel patch 601.
3. Renamed patch 601 (net patch) to 202 (core-linux patch). Maybe it's
more proper.

Some targets need 4K sectors for small flash chips (e.g. some
routerboards, where the entire chip is just one "erase block"), whereas
on other devices 4K sectors lead to horrible flash erase/write
performance.
Set the default limit in the generic kernel configuration to 4 MiB to
ensure that all new platforms don't use 4K sectors for bigger flash
chips. On all existing targets use 16 MiB for now to avoid regressions.
They will be changed individually in follow-up commits.

The NXP LSDK kernel backported changes for interface ndo_get_stats64
functions from mainline, this causes a compile error with
backports/mac80211, which expects the original 4.9 defintion.
As reversing the ndo_get_stats64 change signifcantly reduces the size of
patch 601, the patches that were aggregated into it have been
disaggregated.
