[RESEND PATCH v2 0/3] add regmap & indirect access support

[Xu Yilun <yilun.xu@xxxxxxxxx>]

Updated the regmap & indirect access support for spi-altera.

Patch #1 is an 1:1 replacement of of readl/writel with regmap_read/write
Patch #2 introduced a new platform_device_id to support indirect access as
         a sub device.
Patch #3 is a minor fix.

Main changes from v1:
 - Split the regmap supporting patch to 2 patches.
 - Add a new platform_device_id to support indirect access.
 - Removed the v1 patch "move driver name string to header file". Now we
   use driver name string directly.
 - Add Yilun's Signed-off-by for Patch #3.
 - Add Tom's Reviewed-by.
