Currently if no comm can be found dlm_comm_seq() returns -EEXIST which
means entry already exists for a lookup it makes no sense to return
-EEXIST. We change it to -ENOENT. There is no user that will evaluate
the return value on a specific value so this should be fine.

The return type of srcu_read_lock() is int and not bool. Whereas we
using the ret variable only to evaluate a bool type of
dlm_lowcomms_con_has_addr() to check if an address is already being set.

An rsb struct was not being removed in the case where it
was both the master and the dir record. This case (master
and dir node) was missed in the condition for doing add_scan()
from deactivate_rsb(). Fixing this triggers a related WARN_ON
that needs to be fixed, and requires adjusting where two
del_scan() calls are made.

The header clearly states that it does not want to be included directly,
only via 'device.h'. The 'platform_device.h' works equally well.
Thus, remove the direct inclusion.

Airoha EN7581 has a hardware bug asserting/releasing PCIE_PE_RSTB signal
causing occasional PCIe link down issues. In order to overcome the
problem, PCIE_RSTB signals are not asserted/released during device probe
or suspend/resume phase and the PCIe block is reset using REG_PCI_CONTROL
(0x88) and REG_RESET_CONTROL (0x834) registers available in the clock
module running clk_bulk_prepare_enable in mtk_pcie_en7581_power_up().
Introduce flags field in the mtk_gen3_pcie_pdata struct in order to
specify per-SoC capabilities.

This reverts commit f042bc234c.
A recent change enabling role switching for the x1e80100 USB-C
controllers breaks UCSI and DisplayPort Alternate Mode when the
controllers are in host mode:
ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: PPM init failed, stop trying
As enabling OTG mode currently breaks SuperSpeed hotplug and suspend,
and with retimer (and orientation detection) support not even merged
yet, let's revert at least until we have stable host mode in mainline.

This reverts commit 2dd3250191.
A recent change enabling OTG mode on the x1e81000 CRD breaks suspend.
Specifically, the device hard resets during resume if suspended with all
controllers in device mode (i.e. no USB device connected).
The corresponding change on the T14s also led to SuperSpeed hotplugs not
being detected.
With retimer (and orientation detection) support not even merged yet,
let's revert at least until we have stable host mode in mainline.

mtk_pcie_en7581_power_up().
Reduce reset timeout from 250ms to the standard PCIE_T_PVPERL_MS value
(100ms) since it has no impact on the driver behavior.
