mtd: zynq: nand: Move board_nand_init() function to board.c

Putting board_nand_init() function inside NAND driver was not appropriate
due to it doesn't allow board vendor to customise their NAND
initialization code such as adding NAND lock/unlock code.

This commit was to move the board_nand_init() function from NAND driver
to board.c file. This allow customization of board_nand_init() function.

arm64: zynqmp: Add SMMU support for SATA IP

AXI master interface in CEVA AHCI controller requires two unique
Write/Read ID tags per port. This is because, ahci controller uses
different AXI ID[3:0] bits for identifying non-data transfers(like
reading descriptors, updating PRD tables, etc) and data transfers
(like sending/receiving FIS).To make SMMU work with SATA we need to
add correct SMMU stream id for SATA. SMMU stream id for SATA is
determined based on the AXI ID[1:0] as shown below

SATA SMMU ID =  <TBU number>, 0011, 00, 00, AXI ID[1:0]
Note: SATA in  ZynqMp uses TBU1 so TBU number = 0x1, so
      SMMU ID = 001, 0011, 00, 00, AXI ID[1:0]

Since we have four different AXI ID[3:0] (2 for port0 & 2 for port1
as said above) we get four different SMMU stream id's combinations
for SATA. These AXI ID can be configured using PAXIC register.
In this patch we assumed the below AXI ID values

 Read ID/ Write ID for Non-Data Port0 transfers = 0
 Read ID/ Write ID for Data Port0 transfers = 1
 Read ID/ Write ID for Non-Data Port1 transfers = 2
 Read ID/ Write ID for Data Port1 transfers = 3

Based on the above values,SMMU stream ID's for SATA will be 0x4c0 &
0x4c1 for PORT0, 0x4c2 & 0x4c3 for PORT1. These values needed to be
added to iommus dts property. This patch does the same.

arm64: zynqmp: Fix broken architected timer interrupt trigger

Extract from Linux mainline patch:
The ARM architected timer specification mandates that the interrupt
associated with each timer is level triggered (which corresponds to
the "counter >= comparator" condition).

A number of DTs are being remarkably creative, declaring the interrupt
to be edge triggered. A quick look at the TRM for the corresponding ARM
CPUs clearly shows that this is wrong, and I've corrected those.
For non-ARM designs (and in the absence of a publicly available TRM),
I've made them active low as well, which can't be completely wrong
as the GIC cannot disinguish between level low and level high.

The respective maintainers are of course welcome to prove me wrong.

While I was at it, I took the liberty to fix a couple of related issue,
such as some spurious affinity bits on ThunderX, and their complete
absence on ls1043a (both of which seem to be related to copy-pasting
from other DTs).

mx6sxsabresd: Use PARTUUID to specify the rootfs location

mx6sxsabresd can run different kernel versions, such as NXP 4.1 or mainline.

Currently the rootfs location is passed via mmcblk number and the
problem with this approach is that the mmcblk number for the SD
card changes depending on the kernel version.

In order to avoid such issue, use the UUID method to specify the
rootfs location.
