1. The method to switch output voltage is different in rtl8411
2. Fix the formula to calculate N from SD clock if clock divider is more than 1

Wei WANG (3):
  MFD:rtsx: Add callback function switch_output_voltage
  MMC:rtsx: Using callback function to switch output voltage
  MFD:rtsx: Add callback function conv_clk_and_div_n

Different card reader has different method to switch output voltage,
add this callback to let the card reader implement its individual switch
function.

Different card reader has different method to switch output voltage, so
we have to use the callback function provided by MFD driver to switch
output pad voltage.

From: Wei WANG <wei_wang@realsil.com.cn>

Add callback function conv_clk_and_div_n to convert between SSC clock
and its divider N.
For rtl8411, the formula to calculate SSC clock divider N is different
with the other card reader models.
