pinctrl: stmfx: update pinconf settings
Alignment with kernel driver.
According to the following tab (coming from STMFX datasheet), updates
have to done in stmfx_pinctrl_conf_set function:
-"type" has to be set when "bias" is configured as "pull-up or pull-down"
-PIN_CONFIG_DRIVE_PUSH_PULL should only be used when gpio is configured as
output. There is so no need to check direction.
DIR | TYPE | PUPD | MFX GPIO configuration
----|------|------|---------------------------------------------------
1 | 1 | 1 | OUTPUT open drain with internal pull-up resistor
----|------|------|---------------------------------------------------
1 | 1 | 0 | OUTPUT open drain with internal pull-down resistor
----|------|------|---------------------------------------------------
1 | 0 | 0/1 | OUTPUT push pull no pull
----|------|------|---------------------------------------------------
0 | 1 | 1 | INPUT with internal pull-up resistor
----|------|------|---------------------------------------------------
0 | 1 | 0 | INPUT with internal pull-down resistor

0 | 0 | 1 | INPUT floating
----|------|------|---------------------------------------------------
0 | 0 | 0 | analog (GPIO not used, default setting)
