net: ipa: replace ipa->suspend_ref with a flag bit
We take a clock reference in ipa_config() in order to prevent the
the IPA clock from being shutdown until a power management suspend
request arrives. An atomic field in the IPA structure records
whether that extra reference had been taken.
Rather than using an atomic to represent a Boolean value, define
a new flags bitmap, and define a "clock held" flag to represent
whether the extra clock reference has been taken.
