Commit 7af1fb9faafb ("kernel: add a RPS balancer") introduces a RPS balancer
for all targets.

In the past however, this patch was already introduced for target "mediatek"
in commit 7762c07c8898 ("mediatek: bump to v4.14")

Remove the separate copy of the patch within the mediatek target,
which otherwise is applied twice and results in a build error.

While finalizing support for the U7623 with 512MB, I made an embarresing
error and configured 1GB RAM for the board. I also forgot to move memory
from the dtsi and to the dts. This commit takes care of my mistakes.

While I am confessing my mistakes, I also note that I made a mistake in
the commit message of the initial U7623 commit. It is the .bin-file, and
not the .gz file that shall be sent to the device via tftp.

v1->v2:
* Remove redundant memory node (thanks Jonas Gorski)

In 4.14.57, a new symbol for Spectre v4 mitigation was introduced for
ARM64. Add this symbol to all ARM64 targets using kernel 4.14.

This mitigates CVE-2018-3639 on ARM64.

Drop the parallel-unsafe custom Build/dtb macro and use the .dtb artifacts
produced by the generic image build code.

Also remove unused .dtb references in the mt7623 subtarget.

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

The changed applied to BananaPi R2 in upstream commit c0b0d540db1a,
which was backported to 4.14 in 4.14.53, is also required for the U7623.
Without updating the memory node, the board refuses to boot.
