Konsta Hölttä 1b1d183b9c gpu: nvgpu: simplify gmmu map calls
Introduce nvgpu_gmmu_map_partial() to map a specific size of a buffer
represented by nvgpu_mem, or what nvgpu_gmmu_map() used to do. Delete
the size parameter from nvgpu_gmmu_map() such that it now maps the
entire buffer. The separate size parameter is a historical artifact from
when nvgpu_mem did not exist yet; the typical use is to map the entire
buffer.

Mapping at a certain address with nvgpu_gmmu_map_fixed() still takes the
size parameter.

The returned address still has to be stored somewhere, typically to
mem.gpu_va by the caller so that the matching unmap variant finds the
right address.
