[PATCH v4 2/3] staging: sm750fb: convert logging to device-based in sm750.c

[Artem Lytkin <iprintercanon@gmail.com>]

Replace pr_err() calls with dev_err() using info->device to provide
proper device context in log messages. This makes it easier to
identify which device generated the message when multiple framebuffer
devices are present.
