drm/ssd130x: Implement ssd130x_write_cmd() on top of ssd130x_write_cmds()

Browse source

ssd130x_write_cmd() and ssd130x_write_cmds() each carried their own
regmap_write() loop over SSD13XX_COMMAND, differing only in how the caller
supplies the bytes.

Turn ssd130x_write_cmd() into a thin variadic wrapper that collects its
arguments into a small stack buffer and defers to ssd130x_write_cmds(), and
move the protocol comment onto the latter, which is where the loop now
lives.

No functional change: the bytes sent and the bus transactions used to send
them are identical for every chip on both the I2C and SPI transports.
