linux-5.5_rc7: Set CONFIG_PSTORE=m

This option enables generic access to platform level
persistent storage via "pstore" filesystem that can
be mounted as /dev/pstore.  Only useful if you have
a platform level driver that registers with pstore to
provide the data, so you probably should just go say "Y"
(or "M") to a platform specific persistent store driver
(e.g. ACPI_APEI on X86) which will select this for you.

Switch on, so that we might be able to get dmesg from crashed
systems out of nvram.

Resolves #1249
