stm32mp1: update device tree and gpio functions

Browse source 
Change fdt_check_status function to fdt_get_status.
Update GPIO defines.
Move some functions in gpio driver, instead of dt helper file.
Add GPIO bank helper functions.
Use only one status field in dt_node_info structure including both status
and secure status.
