[PATCH] hw/sd: sdhci: Enable 64-bit system bus capability in the default SD/MMC host controller

[Joanne Koong <joannekoong@gmail.com>]

The default SD/MMC host controller uses SD spec v2.00. 64-bit system bus capability
was added in v2.

In this change, we arrive at 0x157834b4 by computing (0x057834b4 | (1ul << 28))
where 28 represents the BUS64BIT SDHC_CAPAB field.
