This commit finally adds support for the built in SD/MMC controller in IPQ4019 SoC.
Controller is supported by the upstream SDHCI-MSM driver with a minor clock setting patch.
Patch is special to the IPQ4019 and cannot be upstreamed.
LDO and SDHCI node are upstreamed, and LDO node is awaiting to be accepted.

This adds the neon based implementations of AES & SHA256.
For AES, according to the kernel config help:
Use a faster and more secure NEON based implementation of AES in CBC,
CTR and XTS modes.
Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
and for XTS mode encryption, CBC and XTS mode decryption speedup is
around 25%. (CBC encryption speed is not affected by this driver.)
This implementation does not rely on any lookup tables so it is
believed to be invulnerable to cache timing attacks.
...
The observed speedups on ipq40xx are more modest: speedup is around 20%
for CTR mode and for XTS mode encryption, CBC and XTS mode decryption
speedup is around 10%. Measurements were made using tcrypt, with
1024-bytes blocks for CTR & CBC, and 4096-bytes for XTS.
The aes-neon-bs driver uses a fallback for CBC encryption; that fallback
could be either the generic driver written in C, or the scalar arm-asm
one. Even though aes-arm is 1.9% slower, it is more resilient to timing
attacks (the reason for being slower), so it is being included here.
The neon sha256 module increases performance over the generic module by
33%.

Installation
============
Flash factory image from D-Link web UI. Constraints in the D-Link web UI
makes the factory image unnecessarily large. Flash again using
sysupgrade from inside OpenWrt to reclaim some flash space.
Return to stock D-Link firmware
===============================
Partition layout is preserved, and it is possible to return to the stock
firmware simply by downloading it from D-Link and writing it to the
firmware partition.
# mtd -r write dap2610-firmware.bin firmware
Quirks
======
To be flashable from the D-Link http server, the firmware must be larger
then 6MB, and the size in the firmware header must match the actual file
size. Also, the boot loader verifies the checksum of the firmware before
each boot, thus the jffs2 must be after the checksum covered part. This
is solved in the factory image by having the rootfs at the very end of
the image (without pad-rootfs).
The sysupgrade image which does not have to be flashable from the D-Link
web UI may be smaller, and the checksum in the firmware header only
covers the kernel part of the image.

Deactivate CONFIG_SFP for kernel 4.19 in the generic configuration.
The CONFIG_SFP configuration option was not set to anything in the
ath79 build for me, set it to deactivated by default.

This moves some new configuration options to the generic kernel
configuration instead of configuring them for each target on our own.

This patch syncs the 4.19 kernel config since the
KERNEL_STACKPROTECTOR and compiler options are
now part of the 4.19 generic config.

IPQ40xx series has a HW pseudo random number generator built in.
It already has a node in the upstream ipq4019.dtsi so we just need to enable it.
Its driver has been rewritten to use crypto API so we dont have char interface like under 4.14 kernel.

Since 4.19 upstream kernel provides generic SPI-NAND
framework and vendor specific drivers.
Since only users of MT29F are 2 boards with Winbond
W25N01GV SPI-NAND for which support has been backported
from 4.20 we can drop the ever stuck in staging MT29F
driver and instead use the upstream driver.
