Bug Description

SRU Justification:

[Impact]
This change is needed to OPTEE as the FTPM driver requires 2 contiguous SHMEM pages to boot. Without this change the ftpm_tee_probe function will fail.

[Fix]
Change the CONFIG_OPTEE_SHM_NUM_PRIV_PAGES from 1 to 4. Note that other SHMEM structures are allocated out of this OPTEE pool as well.

[Test Case]
Verified the Microsoft TPM 2.0 FTPM is fully functional with this change, running the tpm2-tss Test Suite (mandatory & optional) tests as well as many of the TPM2 Command tools.

[Regression Potential]
This only has an effect if OPTEE is configured/enabled in the kernel.

This bug is awaiting verification that the linux-bluefield/5.15.0-1025.27 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
