fixed EEPROM user-area space checks for FT232R and FT245R chips in ftdi_eeprom_build()

According to FTDI Application Note 121 ("Accessing the EEPROM User Area Of FTDI
Devices"), the FT232R and FT245R chips have a total 48 words (96 bytes) of
user area space available for descriptive strings.

[Note from Thomas Jarosch: That has also been verified with "FT Prog" by Robin]
