74171df1a4 platform: tegra: uss-io-proxy: Migrate to GPIOD 
Upstream commit a55893133830 ("gpiolib: Remove unused
devm_gpio_request()") removed the devm_gpio_request() function and this
breaks the Tegra USS IO Proxy driver. The devm_gpiod_get() function has
been supported in the Linux kernel since v4.3 and now that the legacy
GPIO functions are being removed, migrate the Tegra USS IO Proxy driver
over to using GPIO descriptors.

f01227d4ea drivers: Drop inline from driver remove wrapper 
The driver remove function is a function pointer and therefore, it does
not make sense to define the function as an 'inline'. Update the
coccinelle script and drivers to remove the inline statement.

In Linux v6.11, the 'platform_driver' structure 'remove' callback was
updated to return void instead of 'int'. Update all the impacted drivers
as necessary to fix this.
