Add NAND controller node to LD11 and LD20. Neither of them supports
the CS1 line, so pinctrl is set up for a single CS line.

Follow the recent trend for the license description, and fix the wrongly
stated X11 to MIT.
The X11 license text [1] is explicitly for the X Consortium and has a
couple of extra clauses. The MIT license text [2] is actually what the
current DT files claim.

Reserve enough space below the kernel base.
The assumed address map is:

Compiling the DT file with W=1, DTC warns like follows:
Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property
Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.

Adjust the PHY parameters for more stable access to the eMMC device.

Since commit a89c472d8b ("mmc: sdhci-cadence: Update PHY delay
configuration"), PHY parameters must be specified by DT.
The hard-coded settings have been converted as follows:
- SDHCI_CDNS_PHY_DLY_SD_DEFAULT -> cdns,phy-input-delay-legacy
- SDHCI_CDNS_PHY_DLY_EMMC_SDR -> cdns,phy-input-delay-mmc-highspeed
- SDHCI_CDNS_PHY_DLY_EMMC_DDR -> cdns,phy-input-delay-mmc-ddr
The following have not been moved:
- SDHCI_CDNS_PHY_DLY_SD_HS
this is unneeded in the eMMC configuration
- SDHCI_CDNS_PHY_DLY_EMMC_LEGACY
this is never enabled by the driver as it is covered by
SDHCI_CDNS_PHY_DLY_SD_DEFAULT

These hardware blocks are SoC-specific, so their compatible strings
should be SoC-specific as well. This change has no impact on the
actual behavior since it is controlled by the generic "simple-mfd",
"syscon" compatible strings.

Add a CPU clock to every CPU node and CPU OPP tables to use the
generic cpufreq driver. All the CPUs in each cluster share the
same OPP table.
Note:
clock-latency-ns (300ns) was calculated based on the CPU-gear switch
sequencer spec; it takes 12 clock cycles on the sequencer running
at 50 MHz, plus a bit additional latency.

The System Control node has 0x10000 byte of registers. The current
reg size must be expanded to use the cpufreq driver because the
registers controlling CPU frequency are located at offset 0x8000.

At the first system bring-up, I chose to use spin-table because ARM
Trusted Firmware was not ready for this platform at that moment.
Actually, these SoCs are equipped with EL3 and able to provide PSCI.
Now I finished porting the ATF BL31 for the UniPhier platform, so it
is ready to migrate to PSCI enable method.

arm64: dts: Fix broken architected timer interrupt trigger
This resolves a non-obvious conflict between a bugfix from
v4.8 and a cleanup for the exynos7 platform.
The UniPhier reset controller driver has been merged. Enable it.
Also, replace the fixed-rate clocks with the dedicated clock
drivers.
