Update all documentation to reflect the full set of ftdi_eeprom
config file options:
example.conf:
- Add all missing options: release_number, is_not_pnp, group0-3
drive/schmitt/slew, high_current_a/b, suspend_dbus7,
external_oscillator, power_save, clock_polarity, data_order,
flow_control
- Document %UUID% serial auto-generation
- Add per-chip group-to-bus mapping table and nibble encoding
- Add I2C drive settings example
- Reorganize into logical sections with consistent formatting
doc/EEPROM-structure:
- Add FT232H column (was missing entirely)
- Add FT230X column for drive bytes
- Add I/O drive settings section for bytes 0x0C-0x0D with nibble
encoding and per-chip group layout
- Document FT232H byte 0x01 (FT1284, power save) and CBUS range
README, ChangeLog:
- Add entries for drive settings, boolean fix, FT230X, UUID serial
README.build:
- Add uuid-dev to optional build dependencies
