[PATCH] Revert "leds-pca955x: Remove the unused function pca95xx_num_led_regs()"

[Eddie James]

This reverts commit 38bcb51f81af17a6d40fc135e565fc1fb8aa8e9d. This
function is needed by the hardware blink support just introduced. Also
rename the function to pca955x_num_led_regs to match the rest of the
functions in the driver.

Sorry for the build failure everyone. My series was pretty old so I didn't
have that commit to remove the function. Simple rebase didn't conflict so
I didn't notice. Will make sure to test build *after* rebasing next time.
