Jarkko Nikula be90ae1ba1 i3c: mipi-i3c-hci: Fix number of DAT/DCT entries for HCI versions < 1.1
I was wrong about the TABLE_SIZE field description in the
commit 0676bfebf576 ("i3c: mipi-i3c-hci: Fix DAT/DCT entry sizes").

For the MIPI I3C HCI versions 1.0 and earlier the TABLE_SIZE field in
the registers DAT_SECTION_OFFSET and DCT_SECTION_OFFSET is indeed defined
in DWORDs and not number of entries like it is defined in later versions.

Where above fix allowed driver initialization to continue the wrongly
interpreted TABLE_SIZE field leads variables DAT_entries being twice and
DCT_entries four times as big as they really are.

That in turn leads clearing the DAT table over the boundary in the
dat_v1.c: hci_dat_v1_init().

So interprete the TABLE_SIZE field in DWORDs for HCI versions < 1.1 and
fix number of DAT/DCT entries accordingly.
