At present the SiFive PLIC model "priority-base" expects interrupt
priority register base starting from source 1 instead source 0,
that's why on most platforms "priority-base" is set to 0x04 except
'opentitan' machine. 'opentitan' should have set "priority-base"
to 0x04 too.
Note the irq number calculation in sifive_plic_{read,write} is
correct as the codes make up for the irq number by adding 1.
Let's simply update "priority-base" to start from interrupt source
0 and add a comment to make it crystal clear.

Header guard symbols should match their file name to make guard
collisions less likely.
Cleaned up with scripts/clean-header-guards.pl, followed by some
renaming of new guard symbols picked by the script to better ones.
