SE HMIBSC board is based on Qcom APQ8016 SoC. One of the major
difference from db410c is serial port where HMIBSC board uses UART1 as
the debug console with an RS232 port, patch #2 - #5 adds corresponding
driver support.

Patch #6 adds main HMIBSC board specific bits, features:
- Qualcomm Snapdragon 410C SoC - APQ8016 (4xCortex A53, Adreno 306)
- 2GiB RAM
- 64GiB eMMC, SD slot
- WiFi and Bluetooth
- 2x Host, 1x Device USB port
- HDMI
- Discrete TPM2 chip over SPI

Features enabled in U-Boot:
- RAUC updates (refer [2] for more details)
- Environment protection
- USB based ethernet adaptors

Feedback is very much welcome.

Changes in v3:
- Rebased on top of qcom-next [1].
- Collected some review tags.
- Incorporated misc. comments from Caleb and Stephen.
- Split patch#4 as requested.
- Linux HMIBSC board DTS has already been reviewed here [3], I have
  incorporated that for U-Boot too.

Changes in v2:
- Rebased on top on qcom-next [1].
- Added patch#1 as a fix for generic qcom board support.
- Added patch#4 to enable driving GPIO pins based on pinctrl
  configuration. This replaces the custom GPIO configuration.
- Added proper DTS file for HMIBSC board based on Linux DT pattern.
- Merged board support patches into a single patch#5.
