memory: omap-gpmc: Fix unselectable debug option for GPMC 

Commit 63aa945b10 ("memory: omap-gpmc: Add Kconfig option for debug")
added a debug option for GPMC, but somehow managed to keep it unselectable.

This probably happened because I had some uncommitted changes and the
GPMC option is selected in the platform specific Kconfig.

Let's also update the description a bit, it does not mention that
enabling the debug option also disables the reset of GPMC controller
during the init as pointed out by Uwe Kleine-König
<u.kleine-koenig@pengutronix.de> and Roger Quadros <rogerq@ti.com>.

NOTE: In addition to matching the register setup with the bootloader
you also need to match the GPMC FCLK frequency used by the
bootloader or else the GPMC timings won't be identical with the
bootloader timings.
