Subject: [PATCH] ARM: dts: msm: add primary SPMI Arbiter and SPMI debug bus
 for tuna boards

Add spmi-pmic-arb devices for the primary and secondary SPMI buses
found on tuna.  The primary bus operates at 19.2 MHz and is used
for most of the PMICs. The secondary bus operates at 4.8 MHz
and is used exclusively for charging PMICs. Note that the
secondary bus is not used so it is kept disabled.

Add SPMI debug device and associated child devices for the primary
SPMI interface. This provides consumers with unrestricted access
to the PMIC registers on pre-production devices. This helps
make debugging easier.
