Ryan Malloy 890a38bfa0 Fix BCM4500 I2C address and add hardware diagnostic commands 
Correct BCM4500 I2C address from 0x10 (8-bit wire) to 0x08 (7-bit)
since fx2lib shifts internally. Add i2c_combined_read() with repeated
START for proper BCM4500 register access. Add I2C bus scan (0xB4),
raw read (0xB5), and indirect protocol diagnostic (0xB6) commands.
Single-transaction indirect reads/writes for BCM4500 register protocol.

Verified on hardware: BCM4500 ACKs at 0x08, BOOT_8PSK returns config
0x03. Register reads still return zeros — BCM4500 needs DSP firmware
loaded via LOAD_BCM4500 (0x88) before registers become functional.
