[PATCH v1 3/4] mtd: spi-nor: debugfs: Correct DTR protocol names for 1S-xD-xD modes

[Changhuang Liang <changhuang.liang@starfivetech.com>]

The debugfs protocol names for the mixed DTR modes (1-1-1, 1-2-2,
1-4-4, 1-8-8) currently print the command phase as "1D", i.e. dual
transfer on a single line.  That does not match the protocol
definition: these modes issue the opcode on a single line in single
data rate (S), and only the address, dummy and data phases use DTR
(D).  The "1D" prefix is therefore wrong.

Rename them to "1S-xD-xD" so the names reflect that the first phase
is single-data-rate on one line, consistent with the "8D-8D-8D"
naming for SNOR_PROTO_8_8_8_DTR.

This only changes the strings printed by debugfs; no functional
behavior is affected.
