[PATCH] Revert "USB: serial: ch341: add new Product ID for CH341A"

[Dmytro Bagrii <dimich.dmb@gmail.com>]

This reverts commit 46ee4abb10a07bd8f8ce910ee6b4ae6a947d7f63.

CH341A has three different modes of operation selectable either by
hardware pin connections or by external EEPROM configuration. Each
mode is represented by corresponding product ID:

0x5523: Asyncronous Serial Interface
0x5584: Parallel Printer Interface
0x5512: EPP/MEM Interface

(See "5.3.Function configuration" in datasheet at wch-ic.com/downloads/CH341DS1_PDF.html)

When CH341A is configured as EPP/MEM Interface it appears as 1a86:5512 and being mistakenly
handled by ch341 USB serial driver.

It is possible to use CH341A in EPP/MEM mode only if ch341 module is blacklisted, but it must be
unblacklisted every time to use CH341A as a serial converter. Also obviously it is impossible
to use two CH341A boards in different modes simoultaneously.
