[PATCH 2/2] gpio: stm32: correct the bias management

[Patrick Delaunay]

Use the bias configuration for all the GPIO configurations and not
only for input GPIO, as indicated in Reference manual
(Table 81. Port bit configuration table).

Fixes: 43efbb6a3ebf0223f9eab8d45916f602d876319f ("gpio: stm32: add ops get_dir_flags")
Fixes: f13ff88b61c32ac8f0e9068c41328b265ef619eb ("gpio: stm32: add ops set_dir_flags")
