EDAC/qcom: Correct interrupt enable register configuration

Browse source 
The previous implementation incorrectly configured the cmn_interrupt_2_enable
register for interrupt handling. Using cmn_interrupt_2_enable to configure
Tag, Data RAM ECC interrupts would lead to issues like double handling of the
interrupts (EL1 and EL3) as cmn_interrupt_2_enable is meant to be configured
for interrupts which needs to be handled by EL3.

EL1 LLCC EDAC driver needs to use cmn_interrupt_0_enable register to configure
Tag, Data RAM ECC interrupts instead of cmn_interrupt_2_enable.
