Bug 1948375: iwlwifi: Increase microcodes loading timeout

UBUNTU: SAUCE: iwlwifi: Increase microcodes loading timeout

BugLink: https://bugs.launchpad.net/somerville/+bug/1948375

Intel AX201/AX211 device may not work at boot:

Increase MVM_UCODE_ALIVE_TIMEOUT to 2 seconds can solve the issue.

The PNVM loading can also fail:
[ 5.159949] iwlwifi 0000:00:14.3: loaded PNVM version 4b50f925
[ 5.414211] iwlwifi 0000:00:14.3: Timeout waiting for PNVM load!

Trial and error shows that the MVM_UCODE_PNVM_TIMEOUT also needs to be
bumped to 2 seconds to fully eliminate the issue.

The timeout values are verified by rebooting over 10k times.

UBUNTU: SAUCE: bpf: prevent helper argument PTR_TO_ALLOC_MEM to have offset other than 0

BugLink: https://bugs.launchpad.net/bugs/1956585 (OOB write on BPF_RINGBUF (LP: #1956585))

bpf_ringbuf_reserve is currently the only helper that returns a
PTR_TO_ALLOC_MEM, and bpf_ringbuf_submit and bpf_ringbuf_discard expect
only such pointers.

If some arithmetic is done on those pointers, those functions may corrupt
arbritary memory.

Prevent such argument types from having an offset other than 0.

Also, other valid PTR_TO_MEM should not be accepted as parameters to
bpf_ringbuf_submit and bpf_ringbuf_discard. A different type mechanism
should be used instead, in order to guarantee that only values returned by
bpf_ringbuf_reserve can be used.

UBUNTU: SAUCE: ljca: disable autosuspend by default

BugLink: https://bugs.launchpad.net/bugs/1955383

Because it will cost more than 100ms in PM before calling LJCA
resume when enabling autosuspend, which will make first LJCA transfer
after resume use more than 100ms, we disable autosuspend temporarily.
