Qualcomm driver fixes for v7.0

Fix the length of the PD restart reason string in pd-mapper to avoid
QMI decoding errors, resulting in the notification being dropped.

Fix the newly introduce handling of TBT/USB4 notifications in pmic_glink
altmode driver, as it broke the handling of non-TBT/USB4 DisplayPort
unplug events.

RISC-V soc fixes for v7.0-rc6

Microchip:
More resource leak fixes for unlikely scenarios, and a change to the
auto-update "firmware" driver to prevent it probing on systems with
engineering silicon where it cannot be used.

Use devm_mfd_add_devices() instead of mfd_add_devices() to ensure
child devices are properly removed when the driver unbinds.

Similar to the case of commit d48708500610 ("soc: qcom:
pmic_glink_altmode: Fix SVID=DP && unconnected edge case"), leaving the
TBT altmode makes pmic_glink_altmode report a SVID=TBT && mux_ctrl=0
message.

Said commit reordered the check such that the SVID is processed before
checking for NO_CONN. Rework this to take into account valid values of
mux_ctrl first and hopefully solve this for good..

The commit referenced in Fixes started evaluating the value of
alt_port->mux_ctrl before checking the active SVID. This led to
drm_aux_hpd_bridge_notify() no longer being called for the 'DP unplug'
case.

Perhaps somewhat interestingly, the firmware sends a notification with
SVID=DP, mux_ctrl=MUX_CTRL_STATE_NO_CONN and pin_assignment=0 on
unplug. 'pin_assignment' was previously interpreted as a bitfield
excerpt from the second byte of the DP pg_altmode payload (and stored
as an u8).

That value is used in pmic_glink_altmode_sc8280xp_notify(), decremented
by 1 (DPAM_HPD_A). Previously, this would result in an u8 underflow
that would rollover to 0xff (which prior to the Fixes patch would have
caused a pmic_glink_altmode_safe() and 'disconnected' bridge
notification). That check was removed, without a replacement.

Resolve this issue by making sure the SID=DP && mux_ctrl=NO_CONN combo
once again results in a HPD bridge notification.

It looks element length declared in servreg_loc_pfr_req_ei for reason
not matching servreg_loc_pfr_req's reason field due which we could
observe decoding error on PD crash.

  qmi_decode_string_elem: String len 81 >= Max Len 65

Fix this by matching with servreg_loc_pfr_req's reason field.
