Some fe drivers will have to do additional initialization
in their fe ops.init interfaces when called during resume.
Without the additional initialization, fe and tuner driver
resume fails. A new fe exit flag value DVB_FE_DEVICE_RESUME
is necessary to detect resume case. This patch adds a new
define and changes dvb_frontend_resume() to set it prior to
calling fe init and tuner init calls and resets it back to
DVB_FE_NO_EXIT once fe and tuner init is done.
