qti: spmi_arb: Fix NUM_APID and REG_APID_MAP() argument
The NUM_APID value was derived from kernel device tree sources, but I
made a conversion mistake: the amount of bytes in the APID map is the
total size of the "core" register range (0x1100) minus the offset of the
APID map in that range (0x900). This is of course 0x1100 - 0x900 = 0x800
and not 0x200, so the amount of 4-byte integers it can fit is not 0x80
but 0x200. Fix this and make the math more explicit so it can be more
easily factored out and adjusted if that becomes necessary for a future
SoC.
Also fix a dangerous typo in REG_APID_MAP() where the macro would
reference a random variable `i` rather than its argument (`apid`), and
we just got lucky that the only caller in the current code happened to
pass in a variable called `i` as that argument.

qti: spmi_arb: Fix coverity integer conversion warnings
Coverity warns about the risk of unintended sign-exension in some of the
calculations in spmi_arb.c. While the actual numbers used are small
enough that this cannot happen in practice, it's still a good idea to
clean them up by explicitly making the constants used unsigned.

qti: Add SPMI PMIC arbitrator driver
This patch adds a very rudimentary driver for the SPMI arbitrator used
to access the PMIC. It doesn't support all the controller's actual
arbitration features, so it should probably not be used concurrently
with a running kernel (and it's also not optimized for performance). But
it can be used to set a few registers during boot or on shutdown to
control reset handling, which is all we need it for.
