[PATCH v2 1/2] staging: sm750fb: rename pvReg to mmio

[Jad Keskes <inasj268@gmail.com>]

Rename 'pvReg' to 'mmio', a more meaningful name that reflects its purpose as a memory-mapped I/O pointer. This improves readability and aligns with kernel naming conventions by removing Hungarian notation ('pv').
