Subject: [PATCH] arch: parisc: kernel: sys_parisc:  Remove some unused functions

Removes some functions that are not used anywhere:
parisc_personality() parisc_fallocate() parisc_sync_file_range()
parisc_fadvise64_64() parisc_readahead() parisc_pwrite64() parisc_pread64()
parisc_ftruncate64() parisc_truncate64()

This was partially found by using a static code analysis program called cppcheck.
