Now that the EVM can treat its GPIO expanders as banks of normal
GPIOs (albeit ones that require sleeping accessors), remove the old
LED code in favor of the more generic support.

Declare two of the three I2C GPIO expanders to the EVM board init logic, and
use them.  One hooks up to the LEDs using the leds-gpio driver; the other
exposes a switch to sysfs, and initializes the audio clocks.

The third expander is currently handled by gpio_expander_davinci.c (which
has not yet gone upstream, and probably can't), so a patch to handle that
expander should remove that file and its users.

The I2C EMAC code for reading the MAC address from EEPROM uses
deadbeEf in one place and deadbeAf in others as a magic string. As a
result, all DVEVMs actually get the same default MAC address. Here,
we correct them to the British English spelling of beef to fix the
issue and avoid further confusion (hopefully).

[Sorry, the previous patch was a copy/paste mistake, this one should be
better]

I have no access to the docs for this chip but I'm pretty sure the current
address of the two DIDR1 registers is wrong because it's outside the
TUSB-specific register space.  The modified address in turn has a good
chance to be correct.

While getting trying to get the keyboard driver to accept my
keyboard layout I found and fixed a few bugs.

- Fixed the driver to respect the matrix size and .rep
  fields from "struct omap_kp_platform_data"

- Fixed misc. configuration problems.

- Fixed some problems with the interrupt/polling code by
  implementing 100% event driven scan handling (there
  was a race between the timer and interrupt initiated
  calls to twl_4030_kp_scan()).

- Too many interrupts was delivered -> enable "PENDING_DISABLE".

- The controller would hang with keys stuck on -> program
  KEYP_TIMEOUT so sensible timeout.

Other enhancements:

- Simple ghost key suppression.
- Support for non-matrix switches. That is switches connected
  between GND and a row.

To configure the driver for the non-matrix switches you add the
key as you normally would, but the col-index will have to be the
same value as the col-size.

For example with .cols = 2 and you will use the value "2" for
COL for the two non-matrix switches:

static int rocket_control_keymap[] = {
	/* COL ROW */
	KEY(0,  0, KEY_3),
	KEY(0,  1, KEY_2),
	KEY(1,  0, KEY_1),
	KEY(1,  1, KEY_LAUNCH),
	KEY(2,  0, KEY_ABORT),
	KEY(2,  1, KEY_SD),
	0
}

Cleanup:

I might have gone too far when fixing the twl4030-keypad.h file,
but I was loosing breath and attention spelling my way through
these 32+ letter identifiers with names like:

    BIT_KEYP_CTRL_REG_TOLE_EN_MASK

which is a bit in the register:

   REG_KEYP_CTRL_REG

leading to statements like:

   twl4030_kpwrite_u8(TWL4030_MODULE_KEYPAD,
           BIT_KEYP_CTRL_REG_TOLE_EN_MASK, REG_KEYP_CTRL_REG);

What I did was to take out all the redundant stuff like BIT, REG
and MASK, making reading a little easier:

   twl4030_kpwrite_u8(TWL4030_MODULE_KEYPAD,
                      KEYP_CTRL_TOLE_EN, KEYP_CTRL);

There was a lot of configuration stuff in header file that wasn't
really needed. I think I even found a joke:

.h had this line:
   #define BIT_PTV_REG_PTV4                       (0x4)

.c had this:
       /* Set Pre Scalar Field PTV to 4 */
       reg = BIT_LK_PTV_REG_PTV_MASK & (BIT_PTV_REG_PTV4 << BIT_LK_PTV_REG_PTV);
