[U-Boot] [PATCH v2] dm: pinctrl: fix for introduce PINCONF_RECURSIVE option

Correct the name of the define used CONFIG_IS_ENABLED which is
not aligned with Kconfig name: CONFIG_$(SPL_)PINCONF_RECURSIVE.

The recursive calls is conditional only for UCLASS_PINCONFIG
"pinconfig" driver.
It is always needed to call pinctrl_post_bind for UCLASS_PINCTRL
"pinctrl", the test CONFIG_IS_ENABLED(PINCONF_RECURSIVE) need to
be removed for this driver.

This correct a regression introduced because the same patch is
applied twice times in u-boot-dm branch:
- commit e878b53a79d1 ("dm: pinctrl: introduce PINCONF_RECURSIVE
  option")
- commit c20851b3d850 ("dm: pinctrl: introduce PINCONF_RECURSIVE
  option")

Hi,

This patch solve regression on stm32mp157c-ev1 board (boot failed)
on master branch since Merge tag 'dm-pull-15oct19' of
https://gitlab.denx.de/u-boot/custodians/u-boot-dm

The V1 patch was a partial solution, it solve the first issue
detected on sandbox.

Regards

Patrick

Changes in v2:
- update a second error after tests: don't remove post bind ops for
  pinctrl driver.
