[PATCH 3/4] mci: sdhci: add register define for P_VENDOR_SPECIFIC_AREA

[Yann Sionneau]

This register is standardized by SDHCI (See SD Host Controller
Simplified Specification v4.20 "1.2 Register Map" and
"2.3.14 Pointer Registers to mFFh-100h Area").
 
It is necessary to access some vendor specific registers for
some controllers.
