parisc: Always use the self-extracting kernel feature

This patch drops the CONFIG_PARISC_SELF_EXTRACT option. The palo boot loader is able to decompress a kernel which was compressed with gzip. That possibility was useful when the Linux kernel self-extracting feature wasn't implemented yet. Beside the fact that the self-extracting feature offers much better compression rates, we do support self-extracting kernels already since kernel v4.14, so now it's really time to get rid of that old option and always use the self-extractor.
