Subject: [PATCH 4/4] staging: sm750fb: convert pr_* to dev_* logging in sm750_hw.c

Convert pr_info/pr_err calls to dev_info/dev_err in hw_sm750_map()
and hw_sm750_inithw() where struct pci_dev *pdev is available as
a function parameter. Functions without direct device pointer access
are left unchanged to avoid unnecessary signature changes.
