[coreboot-gerrit] Change in coreboot[master]: drivers/vpd: add support for VPD_RW_OR_RO

[Jonathan Zhang (Code Review)]

Hello Hung-Te Lin, build bot (Jenkins), Johnny Lin, David Hendricks,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/41586

to look at the new patch set (#2).

Change subject: drivers/vpd: add support for VPD_RW_OR_RO

drivers/vpd: add support for VPD_RW_OR_RO

This change is based on the concept that system user's (overwrite)
settings are held in VPD_RW region, while system owner's (default)
settings are held in VPD_RO region.

Add VPD_RW_OR_RO, so that VPD_RW region is searched first to get
overwrite setting, otherwise VPD_RO region is searched to get
default setting.

Rename VPD_ANY to VPD_RO_OR_RW, to reflect the search preference.
Update all existing code references to VPD_ANY.
