NAND support for DaVinci-family drivers, with HW ECC support.
Declare the NAND chip on the DM355 EVM board.
Currently tested on DM355 for Linux interop using the standard
large page (2KB) chip in the EVM socket; "hwecc1" and "hwecc4"
work fine. (Using hwecc4 relies on patches that haven't quite
made it through the Linux-MTD bottlenecks yet.)
Not yet tested: 1-bit on small-page (although it's hard to see
how that could fail); 4-bit on small page (picky layout issues);
the "hwecc_infix" mode (primarily for older boot ROMs; testing
there is blocked on having new bootloader code).

Improve support for the DM355 EVM board, and eventually other boards based
on DaVinci chips:
- Provide generic "davinci.cfg" to hold utilities that can be reused by
different chips in this family. Start with PINMUX, PSC, and PLL setup.
- DM355 chip support updates: provide a dictionary with chip-specific
symbols, load those utilities.
- Create a new dm355evm board file, with a reset-init event handler
which uses those utilities to set up PLLs and clocks, configure the
pins, and improve the JTAG speed limit.
Also a minor tweak: provide a virtual address for the work area, matching
what the very latest kernels do. It's probably unwise to use OpenOCD while
the MMU is active though.
The DRAM isn't yet accessible, but NAND access is mostly ready.
