Subject: [PATCH] leds: pca955x: Remove unused pca95xx_num_led_regs()

Commit 561099a1a2e9 ("leds: pca955x: add GPIO support") removed the
remaining use of pca95xx_num_led_regs(). Recently the kernel test robot
started complaining about the unused symbol after some patches to the
driver were merged[1]. Drop the unused function.
