[PATCH] net: dsa: bcm_sf2: Utilize mask clear/set helpers in bcm_sf2_intr_disable

[Florian Fainelli <f.fainelli@gmail.com>]

From: Florian Fainelli <florian.fainelli@broadcom.com>

And while at it, remove the unecessary writing of zeroes to the CPU_MASK_CLEAR
register since it has no functional use.
