fbdev: platinumfb: add error checking for ioremap calls
The ioremap() and ioremap_wt() calls in platinumfb_probe() were not
checked for failure. If any of these mappings fail, the driver would
dereference NULL pointers, leading to a kernel panic.
Add proper error checking and use goto-based cleanup to avoid code
duplication across the error paths.
