hw/sd: Add SDHC support for SD card SPI-mode
In SPI-mode, SD card's OCR register: Card Capacity Status (CCS) bit
is not set to 1 correclty when the assigned SD image size is larger
than 2GB (SDHC). This will cause the SD card to be indentified as SDSC
incorrectly. CCS bit should be set to 1 if we are using SDHC.
Also, as there's no power up emulation in SPI-mode.
The OCR register: Card power up status bit bit (busy) should also
be set to 1 when reset. (busy bit is set to LOW if the card has not
finished the power up routine.)
