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);
