SVN rev 214349 on 2010-10-25 15:51:43Z by nwhitehorn
The EHCI_CAPLENGTH and EHCI_HCIVERSION registers are actually sub-registers
within the first 4 bytes of the EHCI memory space. For controllers that
use big-endian MMIO, reading them with 1- and 2-byte reads would then
return the wrong values. Instead, read the combined register with a 4-byte
read and mask out the interesting quantities.
