parisc: support R_PARISC_SECREL32 relocation in modules
The parisc kernel doesn't work with CONFIG_MODVERSIONS since the commit 71810db27c1c853b335675bee335d893bc3d324b. It can't load modules with the error: "module unix: Unknown relocation: 41". The commit changes __kcrctab from 64-bit valus to 32-bit values. The assembler generates R_PARISC_SECREL32 secrel relocation for them and the module loader doesn't support this relocation. This patch adds the R_PARISC_SECREL32 relocation to the module loader.
