[spi_device] Latch flip event only when active
Problem:
`flip` occurs regardless of the buffer's active state. Buffer is
active only when the read command sends output to the host system.
`flip` sees the address being latched while address is shifted in to
the register. It causes premature flip event, which in turn results
in the incorrect watermark event.
Revised the `flip` logic to latch only when the read buffer manager is
active.

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
