HCIVERSION:
This is a two-byte register containing a BCD encoding of the xHCI
specification revision number supported by this host controller. The most significant byte
of this register represents a major revision and the least significant byte is the minor
revision. e.g. 0100h corresponds to xHCI version 1.0.xs

MAXPORTS:
Number of Ports (MaxPorts). This field specifies the maximum Port
Number value, i.e. the highest numbered Port Register Set that are addressable in the
Operational Register Space (refer to Table 29). Valid values are in the range of 1h to
FFh. The value in this field shall reflect the maximum Port Number value assigned by an
xHCI Supported Protocol Capability, described in section 7.2. Software shall refer to
these capabilities to identify whether a specific Port Number is valid, and the protocol
supported by the associated Port Register Set.
