Use the common PCIEXP_HOTPLUG code to generate a dummy device for PCIe
ports supporting hotplug. This allows to have control over how much
resources are allocated to hotplug ports.
Tested on thinkpad X220: now hotplugging a dGPU via the expresscard
slot sometimes works.

TCSS muxes being left uninitialized during boot is causing some USB3

the muxes should be set to disconnected state during boot so that the port

devices.

The datasheet indicates that this bit is reserved. However, subsequent
patches need to use this macro in common code, or else builds fail. To
iron out this difference, mask out the bit in `soc_get_smi_status`, so
that common code always sees it as zero. Finally, add an entry for the
bit in `smi_sts_bits` for debugging usage, noting that it is reserved.

`pmc_send_ipc_cmd()` expects the caller to pass in a pointer to a valid
request and response buffer. However, early_tcss driver was passing in
a NULL pointer for response buffer which would result in invalid
access by `pmc_send_ipc_cmd()`.
Currently, the response buffer is not used in `update_tcss_mux()`. So,
this change drops the passing of `rbuf` parameter to `send_pmc*`
helpers and instead uses a local `rsp` variable in the respective
functions. All the PMC functions used in early_tcss driver return some
kind of response. These should be checked to return appropriate
response code back to the caller. However, this needs to be done as a
separate change.

In commit 2609eaaa8f (src/drivers/i2c/rx6110sa: Omit _HID temporarily)
the randomly assigned and therefore wrong ACPI ID for RTC RX6110SA was
removed. In the meantime Seiko-Epson did a great job and registered an
official vendor ID in the ACPI database [1]. Further on, Seiko-Epson
has now assigned the unique Product Identifier for the RX6110SA, which
is '6110'. The assignment of the Product Identifier is controlled by
the vendor and there is no official database where this ID is stored
in. It is up to the vendor to make sure that this ID stays unique.
This patch adds this new vendor and product ID to the driver. Together
with a pending Linux patch this RTC is now useable as ACPI device in
Linux.
