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

In order to have a smaller initramfs image remove all packages not
needed on all devices and add them explicitely for those actually
needing them. Also remove wpad-mini from ramips default package set
and add it to all sub-targets except for MT7621.
While at it reorder packages alphabetically and replace kmod-mt76 with
kmod-mt7603 and/or kmod-mt76x2 depending on the chip actually used on
a specific board.
Hopefully fixes FS#758

While rt288x only has a MIPS 4KEc processor, it implements the MIPS32r2
architecture just like the 24Kc, so the instruction set should be 100%
compatible.
Switching it to 24kc allows it to share the package architecture with a
lot of other targets instead of creating a special case, saving
buildbot resources.

All known rt305x and rt3883 implementations support at
least the 24kec instruction set which includes the DSP
extension. For rt288x, the previous value mips32r2 is
kept.
The cpu target is now set per sub-archtecture, according
to cpu-feature-overrides.h of each SoC family.
[juhosg: define ARCH_PACKAGES variable for rt305x/rt3883
in order to differentiate the packages compiled with
the 24Kec option.]
