[U-Boot] [PATCH v3 2/2] gpio: omap_gpio: Fix valid GPIO range for OMAP5

[Axel Lin]

OMAP54XX and DRA7XX SoCs have 8 banks per 32 GPIOs, that is, 256 in total.
The DRA7xx config defines CONFIG_DRA7XX, but also includes omap5_common.h,
where CONFIG_OMAP54XX is defined (due to sharing of many internal IPs with
the OMAP5, including GPIO).

v3: just a new patch adding to this patch serial.

Hi Lubomir,
I'd appreciate if you can test this patch serial ( mainly for OMAP5 ).

Thanks,
Axel
