MSM8916 is the only ARM64 Qualcomm SoC that is still using the old
&msmgpio name. Change this to &tlmm to avoid confusion.
Note that the node ordering does not change because the MSM8916 device
trees have pinctrl separated at the bottom (similar to sc7180).

DT schema expects TLMM pin configuration nodes to be named with
'-state' suffix and their optional children with '-pins' suffix.

On the Samsung Galaxy E5 and E7 the touch key is supplied by a single
fixed regulator (enabled via GPIO 97) that supplies both MCU and LED.
Add it to the device tree.

Samsung Galaxy E5, E7 and Grand Max are smartphones using the MSM8916 SoC
released in 2015.
e2015 and a2015 are similar, with some differences in accelerometer,
MUIC and Vibrator. The common parts are shared in
msm8916-samsung-a2015-common.dtsi to reduce duplication.
Add a common device tree for with initial support for:
- GPIO keys
- GPIO LEDs for Grand Max
- Regulator haptic
- Hall sensor (except Grand Max)
- SDHCI (internal and external storage)
- USB Device Mode
- UART (on USB connector via the SM5504 MUIC)
- WCNSS (WiFi/BT)
- Regulators
- S3FWRN5 NFC (except Grand Max)
The three devices (and all other variants of E5/E7/Grand Max released in
2015) are very similar, with some differences in display, touchscreen,
sensors and NFC. The common parts are shared in
msm8916-samsung-e2015-common.dtsi to reduce duplication.
Unfortunately, some E5/E7/Grand Max were released with outdated 32-bit
only firmware and never received any update from Samsung. Since the 32-bit
TrustZone firmware is signed there seems to be no way currently to
actually boot this device tree on arm64 Linux on those variants at the
moment.
However, it is possible to use this device tree by compiling an ARM32
kernel instead. The device tree can be easily built on ARM32 with
an #include and it works really well there. To avoid confusion for others
it is still better to add this device tree on arm64. Otherwise it's easy
to forget to update this one when making some changes that affect all
MSM8916 devices.
Maybe someone finds a way to boot ARM64 Linux on those device at some
point. In this case I expect that this device tree can be simply used
as-is.
