staging: sm750fb: remove debug and diagnostic prints

Remove all pr_info, pr_debug, and pr_warn calls that dump internal
variable values, pointer addresses, and structure contents not useful
for production use. This includes the complete fb_find_mode() result
logging in lynxfb_set_fbinfo(), the CH7301 DVI chip status messages
in hw_sm750_inithw(), and various debug prints throughout the driver.
