A platform device can be used to provide some specific resources in
order to manage the controller. In this first patch we retrieve the
reset gpio which is used to power on/off the controller.
The main issue is to match the current tty with the correct pdev.
In case of ACPI, we can easily find the right tty/pdev pair because
they are both child of the same UART port.
If controller is powered-on from the driver, we need to wait for a
HCI boot event before being able to send any command.

Implement the set_baudrate callback for hci_intel.
- Controller requires a read Intel version command before updating
its baudrate.
- The operation consists in an async cmd since the controller does
not respond at the same speed.
- Wait 100ms to let the controller change its baudrate.
- Clear RTS until we change our own UART speed
Manage speed change in the setup function, we need to restore the oper
speed once chip has booted on patched firmware.

This patch creates a new script (compaction-times) to report time
spent in mm compaction. It is possible to report times in nanoseconds
(default) or microseconds (-u).
The option -p will break down results by process id, -pv will further
decompose by each compaction entry/exit.
For each compaction entry/exit what is reported is controlled by the
options:
-t report only timing
-m report migration stats
-ms report migration scanner stats
-fs report free scanner stats
The default is to report all.
Entries may be further filtered by pid, pid-range or comm (regex).
The script is useful when analysing workloads that compact memory. The
most common example will be THP allocations on systems with a lot of
uptime that has fragmented memory.
This is an example of using the script to analyse a thpscale from
mmtests which deliberately fragments memory and allocates THP in 4
separate threads
