[PATCH -next] spmi: pmic-arb: revert "validate type when mapping IRQ"

[Brian Masney]

Validation of the IRQ type was added to spmi pmic-arb, however spmi-mpp
in device tree still uses IRQ_TYPE_NONE. This commit caused the
spmi-mpp probe to fail since platform_irq_count() would return 0.
Correct this by backing out the previous patch.

Linus: I think that the better longer-term approach is to just embed the
IRQ counts similar to what is now in spmi-gpio. Since we are getting
close to the end of the dev cycle, I think it is safer to just drop
the old patch for the time being. I'll commit to doing that work for the
next dev cycle, although I can send you that change this weekend if you
prefer that we go that route instead.

My ssbi-gpio series does not have this issue.
