ff5405f690 mlxsw: spectrum_acl: Avoid size check for RX_ACL_SYSTEM_PORT element
RX_ACL_SYSTEM_PORT is 8 bit but SRC_SYS_PORT is 16 bits. Internally,
SRC_SYS_PORT is used to carry the value. Relax the checker in case of
RX_ACL_SYSTEM_PORT and allow different size.

511a5adcaa mlxsw: spectrum_acl: Write RX_ACL_SYSTEM_PORT acl element correctly
RX_ACL_SYSTEM_PORT is equal to SRC_SYS_PORT - 1. So before write to
block we need to adjust the key value. Introduce new "EXT" helper to
implement this.

Add virtual router ID fields to Spectrum-2 key blocks set, as the field is
required for multicast routing.

b1ce60e621 mlxsw: spectrum: acl: Don't encode the key again in mlxsw_sp_acl_atcam_12kb_lkey_id_get()
No need to do key encoding again in
mlxsw_sp_acl_atcam_12kb_lkey_id_get(). Instead of that, introduce
a new helper that would just clear unused blocks.

3bc6f3858a mlxsw: core_acl: Change order of args of ops->encode_block()
Change order so it is aligned with the usual case where the "write_to"
buffer comes as the first arg.

a6d70a878e mlxsw: spectrum_acl: Prepare for Spectrum-2 block encoding
In Spectrum the key (and mask) block layout is very straight forward and
every block is 16 bytes aligned.

However, in Spectrum-2 the blocks are not even byte aligned, which makes
it difficult to encode them using current method.

Instead, first encode each block and then encode the block in the
general blocks layout.
