Let's add minimal support for droid 4 with MMC and WLAN working.
It can be booted with appended dtb using kexec to a state where
MMC and WLAN work with currently no support for it's PMIC or
display.

Note that we are currently using fixed regulators as we don't
have support for it's cpcap PMIC. I'll be posting regmap_spi
based minimal cpcap patches later on for USB and the debug
UART on droid 4 multiplexed with the USB connector.

The DRA718-evm is a board based on TI's DRA718 processor targeting
BOM-optimized entry infotainment systems and is a reduced pin and
software compatible derivative of the DRA72 ES2.0 processor.
This platform features:
- 2GB of DDR3L
- Dual 1Gbps Ethernet
- HDMI,
- uSD
- 8GB eMMC
- CAN
- PCIe
- USB3.0
- Video Input Port
- LP873x PMIC

More information can be found here[1].

Adding support for this board while reusing the data available in
dra72-evm-common.dtsi.

dra72-evm-common.dtsi consolidates dra72-evm.dts and dra72-evm-revc.dts
which also include tps65917 pmic support as both the evms uses the same
pmic. But, dra71-evm has mostly similar features with a different pmic.
In order to exploit dra72-evm-common.dtsi, creating a separate dtsi
for tps65915 support and including it in respective board files.

Pinmuxing for DRA7x/AM57x family of processors need to be done in IO
isolation as part of initial bootloader executed from SRAM. This is
done as part of iodelay configuration sequence and is required due
to the limitations introduced by erratum ID: i869[1] (IO Glitches
can occur when changing IO settings) and elaborated in the Technical
Reference Manual[2] 18.4.6.1.7 Isolation Requirements.

Only peripheral that is permitted for dynamic pin mux configuration
is MMC and DCAN. MMC is permitted to change to accommodate the
requirements for varied speeds (which require IO-delay support in
kernel as well). DCAN is a result of i893[1] (DCAN initialization
sequence). With the exception of DCAN and MMC, all other pin mux
configurations are removed from the dts.

The change adds a new device node with description of generic SRAM
on-chip memory found on NXP LPC32xx SoC series and connected to AHB
matrix slave port 3.

Note that NXP LPC3220 SoC has 128KiB of SRAM memory, the other
LPC3230, LPC3240 and LPC3250 SoCs all have 256KiB SRAM space,
in the shared DTSI file this change specifies 128KiB SRAM size.

Also it's worth to mention that the SRAM area contains of 64KiB banks,
2 banks on LPC3220 and 4 banks on the other SoCs from the series, and
all SRAM banks but the first one have independent power controls,
the description of this feature will be added with the introduction of
power domains for the SoC series.
