Vedashree Vidwans bc2ee54301 gpu: nvgpu: Add check for invalid nvgpu_aperture ...

Currently, in nvgpu_aperture_mask_raw function, if NVGPU_MM_HONORS_APERTURE
flag is disabled, invalid or junk aperture input is changed to APERTURE_VIDMEM
instead of raising a warning.To resolve this bug, need to check if input
aperture is APERTURE_INVALID or undefined.

This patch adds APERTURE_MAX_ENUM to nvgpu_aperture structure which
gives upperbound of nvgpu_aperture types. This patch also adds condition in
nvgpu_aperture_mask_raw function to check for invalid or undefined aperture
input. For invalid inputs, function will BUG().
