fc-shell TCH DL handler: add support for CSD modes TCH DL capture mechanism in FC Tourmaline firmware has been extended to support CSD modes in addition to speech - add the necessary support on the host tools side. It needs to be noted that this mechanism in its present state does NOT provide the debug utility value that was sought: as we learned only after the code was implemented, TI's DSP has a misfeature in that the buffer we are reading (a_dd_0[]) is zeroed out when the IDS block is enabled, i.e., we are reading all zeros and not the real DL bits we were after. But since the code has already been written, we are keeping it - perhaps we can do some tests with IDS disabled.

# The following parameters go into the <p command sent to the boot ROM
pll-config 4/1		# 26 MHz in, PLL&DSP @ 104 MHz, ARM @ 52 MHz
rhea-cntl 0x00		# good for all Calypso platforms

# The remaining settings are carried out via loadagent commands
init-script chimei.init

# Chi-Mei phones have a single-bank flash chip on nCS0,
# some phones are 4 MiB, others are 8 MiB.
# We use the usual 0x03000000 mapping like on other targets.
