soc/mediatek/mt8196: Add booker driver

The MediaTek booker (the customized ARM CI-700) is a high-performance
interconnect architecture designed for multi-core processor systems,
providing high bandwidth, low latency data transfer. And booker mainly
uses CHI protocol, but doesn't support coherence (which is achieved
through ACP solution). Additionally, the booker also uses other
protocols such as AXI, which translates CHI transactions into EMI's AXI
transactions.

Currently, the mt8196 booker only uses the functions of SLC CMO routing.
If downstream SLC needs CMO command propagation from the DSU, it is
needed to clear bit 3 (disable_cmo_prop) in por_sbsx_cfg_ctl register of
each SBSX node in order to propagate the CMO command.

TEST=build pass, check boot log with:
[booker_init] AP hash rule: 0xbe00.
BUG=b:317009620
