Add 'volatile' qualifier to new CSR accessors

Add 'volatile' qualifier to new CSR accessors
...
Through their use of the MMPTR() macro, the "classic"
csr_[read|write]simple() accsessors identify the MMIO
subregister with the 'volatile' qualifier.
Adjust the new, csr_[rd|wr]_uint[8|16|32|64]() accessors
to also utilize the 'volatile' qualifier. Since accesses
are implicit (a[i], where a is an 'unsigned long *'),
change 'a' to be a 'volatile unsigned long *' instead.
No difference was noticed in opcodes generated using the
gcc9 risc-v cross-compiler on x86_64 with standard LiteX
cflags (vexriscv and rocket were tested), but since
reports exist that 'volatile' matters on some combinations
of compilers and targets, add the 'volatile' qualifier just
to be on the safe side.

doc: fix regression with new irq manager
...
Previously, we were accessing the `soc.soc_interrupt_map` property in
order to be able to enumerate the interrupts. This has been subsumed
into a more general `irq` object that manages the interrupts.
Use `soc.irq.locs` instead of `soc.soc_interrupt_map` as the authority
on interrupts for both doc and export.
This fixes #385 .
