usb: ci13xxx_msm_hsic: Fix HSIC Connect sequence

With changes how gadget framework works and binding of composite
framework with UDC driver, it is required to handle different
events (STARTED and CONNECT) and perform correct operation to
handle below cases :
1. On boot up, HSIC Core needs to be in LPM.
2. On enabling HSIC composition, bring HSIC core out of LPM and do
connect signaling with HSIC host.

This change also ignores core_clk_always_on_workaround usage.
