Revert "usb: pl2303: also use the divisor based baud rate encoding method for baud rates < 115200 with HX chips"
This reverts commit 61fa8d694b
.
Revert all of the pl2303 changes that went into 3.12-rc1 and -rc2 as
they cause regressions on some versions of the chip. This will all be
revisited for later kernel versions when we can figure out how to handle
this in a way that does not break working devices.
