Revert "leds-pca955x: Remove the unused function pca95xx_num_led_regs()"
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.
