Add a set of tests for the new gpio-sim module. This is a pure shell
test-suite and uses the helper programs available in the gpio selftests
directory. These test-cases only test the functionalities exposed by the
gpio-sim driver, not those handled by core gpiolib code.

Implement a new, modern GPIO testing module controlled by configfs
attributes instead of module parameters. The goal of this driver is
to provide a replacement for gpio-mockup that will be easily extensible
with new features and doesn't require reloading the module to change
the setup.

Software nodes allow us to represent hierarchies for device components
that don't have their struct device representation yet - for instance:
banks of GPIOs under a common GPIO expander. The core gpiolib core
however doesn't offer any way of passing this information from the
drivers.
This extends struct gpio_chip with a pointer to fwnode that can be set
by the driver and used to pass device properties for child nodes.
This is similar to how we handle device-tree sub-nodes with
CONFIG_OF_GPIO enabled.

Currently all users of gpiod_add_hogs() call it only once at system
init so there never was any need for a mechanism allowing to remove
them. Now the upcoming gpio-sim will need to tear down chips with hogged
lines so provide a function that allows to remove hogs.

After processing an interrupt event and the interrupt function is
enabled by writing the QM_DOORBELL_CMD_AEQ register, the hardware
may generate new interrupt events due to processing other user's task
when the subsequent interrupt events have not been processed. The new
interrupt event will disrupt the current normal processing flow and
cause other problems.
Therefore, the operation of writing the QM_DOORBELL_CMD_AEQ doorbell
register needs to be placed after all interrupt events processing
are completed.

When remove the driver and executing the task occur at the same time,
the following deadlock will be triggered:
Chain exists of:
sva_lock --> uacce_mutex --> &qm->qps_lock
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(&qm->qps_lock);
lock(uacce_mutex);
lock(&qm->qps_lock);
lock(sva_lock);
And the lock 'qps_lock' is used to protect qp. Therefore, it's reasonable
cycle is to continue until the qp memory is released. So move the release
lock infront of 'uacce_remove'.

Add new module parameter to allow users to use SEV_INIT_EX instead of
SEV_INIT. This helps users who lock their SPI bus to use the PSP for SEV
functionality. The 'init_ex_path' parameter defaults to NULL which means
the kernel will use SEV_INIT, if a path is specified SEV_INIT_EX will be
used with the data found at the path. On certain PSP commands this
file is written to as the PSP updates the NV memory region. Depending on
file system initialization this file open may fail during module init
but the CCP driver for SEV already has sufficient retries for platform
initialization. During normal operation of PSP system and SEV commands
if the PSP has not been initialized it is at run time. If the file at
'init_ex_path' does not exist the PSP will not be initialized. The user
must create the file prior to use with 32Kb of 0xFFs per spec.
