the ps8xxx family of TCPCs (ps8751, ps8805) have historically used the generic tcpci_tcpm_drv functions, but we need to override some of these entry points because the parade parts need to be woken up before accessing registers. in most cases, this doesn't matter because we access the chip in quick succession where we can "safely" assume the chip is awake -- and the code is structured to implicitly keep the chip awake. the new case we need to address here is where we need to suspend the pd_task and TCPC at an arbitrary point in time. the driver's .release method is called to shut down the chip, and that involves first waking up the chip to be able to access its regs to mask off interrupts, etc. BUG=b:35586896 BRANCH=none TEST=tested from depthcharge - we no longer get errors in the EC console logs about TCPC "release" failed.
