pull-request: Fixes: b2b56a163230 ("gpio: tegra186: Check GPIO pin permission before access.")

[Brad Figg]

The controller has several register bits describing access control
information for a given GPIO pin. When SCR_SEC_[R|W]EN is unset, it
means we have full read/write access to all the registers for given GPIO
pin. When SCR_SEC[R|W]EN is set, it means we need to further check the
accompanying SCR_SEC_G1[R|W] bit to determine read/write access to all
the registers for given GPIO pin.

This check was previously declaring that a GPIO pin was accessible
only if either of the following conditions were met:

  - SCR_SEC_REN + SCR_SEC_WEN both set

    or

  - SCR_SEC_REN + SCR_SEC_WEN both set and
    SCR_SEC_G1R + SCR_SEC_G1W both set

Update the check to properly handle cases where only one of
SCR_SEC_REN or SCR_SEC_WEN is set.
