Subject[PATCH] misc: rtsx: Relocate to misc and add RTS5260 support
Date
From: rui_feng <rui_feng@realsil.com.cn>

1.Move from mfd to misc
Create a folder realtek to store rtl8411.c rts5209.c
rts5227.c rts5229.c rts5249.c rtsx_pcr.c rtsx_pcr.h
Move include/linux/mfd/rtsx_common.h and include/linux/mfd/rtsx_pci.h
to include/linux
Move all Kconfig and Makefile related to Realtek card readers to misc
2.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.
