Changes since v3:
 - constrain gpio-reserved-ranges to 1-75 items
 - proper indentation in dt-bindings example (actually tagged this time
   instead of an outdated commit)
 - remove unnecessary commit reference
 - rename complement_fw_reserved_gpios -> complement_fw_gpio_ranges

Changes since v2:
 - remove quotes from pinctrl.yaml# in dt-bindings
 - constrain gpio-reserved-ranges to 1-76 items (includes ufs_reset)
 - indentation in dt-bindings example
 - cite downstream kernel source
 - remove MODULE_AUTHOR (most imported pinctrl drivers don't have this)

Changes since v1:
 - add a field in msm_pinctrl_soc_data to accomodate the needs of the
   driver and device dts
 - apply changes made to existing tlmm dt documentation
 - add reserved gpios array
 - rename device tree compat string to qcom,sdm670-tlmm
 - remove dependency on ACPI
 - move MODULE_DEVICE_TABLE macro call up
 - add missing pins (fixes most of the debugfs problems)
 - move qup0_pins down
 - add whitespace between UFS_RESET macro and pins array

This patch series adds the driver for the Qualcomm Snapdragon 670 TLMM
(Top-Level Mode Multiplexer) and introduces a new field so that SDM670-
related device trees can reserve their own gpios.
