94116f8126 ACPI: Switch to use generic guid_t in acpi_evaluate_dsm()
acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16
bytes. Instead we convert them to use guid_t type. At the same time we
convert current users.

acpi_str_to_uuid() becomes useless after the conversion and it's safe to
get rid of it.

0c1849a8c7 usb: Add driver for UCSI
USB Type-C Connector System Software Interface (UCSI) is
specification that defines the registers and data structures
that can be used to control USB Type-C ports on a system.
UCSI is used on several Intel Broxton SoC based platforms.
Things that UCSI can be used to control include at least USB
Data Role swapping, Power Role swapping and controlling of
Alternate Modes on top of providing general details about
the port and the partners that are attached to it.

The initial purpose of the UCSI driver is to make sure USB
is in host mode on desktop and server systems that are USB
dual role capable, and provide UCSI interface.

The goal is to integrate the driver later to an USB Type-C
framework for Linux kernel, and at the same time add support
for more extensive USB Type-C port control that UCSI offers,
for example data role swapping, power role swapping,
Alternate Mode control etc.

The UCSI specification is public can be obtained from here:
