usb: typec: fusb302: fix i_comp and i_bc_lvl interrupt

Browse Source 
The software utilizes I_COMP and I_BC_LVL interrupts to determine an
attach and what type of port is attached. and I_COMP interrupt also
alerts software that a SRC detach has occurred. So unmask I_COMP for
SRC and I_BC_LVL for SNK.
