net: dsa: motorcomm: Add TC prio support
The HW orders ACL rules by the 9-bit ORD field (512 values, larger
matching first), while TC priorities span 1..U16_MAX with the smallest
meaning the highest. Map them as evenly as possible, and reject others
which do not map onto a hardware order instead of silently colliding
with a neighbouring one.

net: dsa: motorcomm: Fix MIB synchronization
The previous MIB sync was based on the false assumption that 64-bit
variables are always atomic. To fix that:
* .get_stats64() uses u64_stats_sync, together with u64_stats_t;
* others take the free mutex lock if possible.
To minimize time of the write side of u64_stats_sync, a per-port buffer
is used so that all the stat can be written back altogether after all IO
operations.
The odds of this issue are very low and it does not affect the control
flow, while fixing it would require a thorough refactoring (together with
the previous commit), so it may not be worth backporting.

With MIB improvement introduced later, struct yt921x_priv will be over

net: dsa: motorcomm: Identify port type at runtime
The yt921x_port_is_internal/external() macros hardcoded the port layout:
they treat ports 8 and 9 as external on every chip and count the dummy
ports as internal.
Identify the actual port capabilities using chip info and track
configuration of external ports (although only SerDes is supported now).
This is a hardening and cleanup step ahead of the SerDes PCS support, no
behavior changes intended.
