Fix a long standing bug which regarded some revisions of controller

Browse Source 
as 5788. This caused BGE_MISC_LOCAL_CTL register is used to
generate link state change interrupt for non-5788 controllers. The
interrupt handler may or may not detect link state attention as
status block wouldn't be updated when an interrupt was generated
with BGE_MISC_LOCAL_CTL register. All controllers except 5700 and
5788 should use host coalescing mode register to trigger an
interrupt.
