misc: rtsx: Add support for RTS5260
Add support for new chip rts5260. In order to support rts5260, the definitions of some internal registers and workflow have to be modified and are different from its predecessors and OCP function is added for RTS5260. So we need this patch to ensure RTS5260 can work.
