search for gpio label if gpio name from bankname is not found.
This makes sense on boards with different hardware verions. You can now search for the gpio label name, and can give the gpio a unique name. The real gpio pin number is not needed in board code anymore.
while at it add basic gpio hog test functions in seperate patch.

Changes in v6: - add reviewed by from Patrick and Fixes tag - add Reviewed-by tag from Simon - add additional comments from Simon: - remove "default n" in Kconfig for SPL_DM_GPIO_LOOKUP_LABEL - type of function in same line as the function - add negativ test, where label is not found
Changes in v5: - add comment from patrick, update the descriptor flags in _dm_gpio_set_dir_flags() if setting direction was OK. - add Reviewed-by tag from Simon
Changes in v4: - new in version 4 - rebased to current master ac14bc4169 - rebased to current master ac14bc4169
Changes in v3: - add comment from Simon Glass make this new function configurable through Kconfig option DM_GPIO_LOOKUP_LABEL
Changes in v2: - add basic gpio hog test functions - add comment from Simon Glass move code into seperate function dm_gpio_lookup_label() add test if dm_gpio_lookup_label() works
Heiko Schocher (3): gpio-uclass.c: save the GPIOD flags also in the gpio descriptor sandbox, test: add test for GPIO_HOG function gpio: search for gpio label if gpio is not found through bank name
