[PATCH] gpio: bcm281xx: Use "unsigned gpio" consistently throughout the code

[Markus Mayer]

This patch removes some inconsistencies caused by the use of "int gpio"
in some parts of the code and "unsigned gpio" in others.

Patch applied, nice for static syntax checkers.

But the variable should probably be renamed from
"gpio" to "offset" since it's a local offset number on this
very GPIO block, not the global GPIO numberspace.

No big deal though.
