[PATCH V1] gpio: fix bits conflict for gpio flags

[Laxman Dewangan]

The bit 2 and 3 in GPIO flag are allocated for the
flag OPEN_DRAIN/OPEN_SOURCE. These bits are reused
for the flag EXPORT/EXPORT_CHANGEABLE and so creating
conflict.
Fix this conflict by allocating bit 4 and 5 for the
flag EXPORT/EXPORT_CHANGEABLE.
