serial: 8250, increase PASS_LIMIT
With virtual machines like qemu, it's pretty common to see "too much
work for irq4" messages nowadays. This happens when a bunch of output
is printed on the emulated serial console. This is caused by too low
PASS_LIMIT. When ISR loops more than the limit, it spits the message.
I've been using a kernel with doubled the limit and I couldn't see no
problems. Maybe it's time to get rid of the message now?
