ARM: Tegra: Defined ARCH_NR_GPIOS for tegra chip
The default value of ARCH_NR_GPIOS is defined to 256. That is not enough
for Tegra based board such as ventana. Ventana has 224 gpios on Tegra
soc and other gpio expanders like PMU and audio codecs. Extended GPIO
numbers to make external gpio pins work.
