Allow callers to select native, low-high, or high-low access for xHCI 64-bit MMIO registers. Keep native access as the default for existing users while making split access available for platforms and controllers that cannot accept native 64-bit MMIO operations.
The USB legacy support control/status register is the second dword of the capability. Map it at base + 4 instead of aliasing the legacy support semaphore register.
The Doorbell Array contains entry zero for the host controller followed by one entry for each device slot. Include that first entry in the accessor length so the highest valid slot ID remains addressable.

The Doorbell Array starts with the host controller doorbell, followed by one entry for each device slot. The current length only accounts for the device slots, which leaves the highest valid slot ID out of bounds.
Include entry zero in the array length and cover access to the last device doorbell.
