This enables using 4kiB sectors as erase blocks for 4MiB NOR flash ICs
that support it.
Writeable jffs2 overlay used to store settings requires a partition with
at least 5 erase blocks, so using small sectors is essential for devices
with 4MiB flash.
Sysupgrading a device running firmware without this feature will likely
not allow to preserve configs automatically but since ath79 is
considered to be in a "technology preview" state it shouldn't be a
problem.

This commit adds PCI support for the whole ath79 target. Previously,
this was only done in the generic and tiny subtargets.
With the introduction of the HiveAP-121, PCI will be a requirement for
all subtargets, thus moving PCI support to the target configuration.

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
