The driver currently supports only I2C access. But supported devices with an
accuracy of 8-bit are compatible with the SMBus byte access routines.

This patch wraps the send and receive routines depending on the chip
accuracy and fonctionnalities of its adapter.

For instance, this allows us to use a MAX11603 on a ICH7 controller.

This patch also simplifies the max1363_write_basic_config() routine to
use the struct max1363_state fields directly.

this just fixes the comment; however, I'm not sure if the driver reports
measurements correctly; the raw values are 0.3 uT / LSB; IIO is supposed
to report magnetic fields in Gauss, so the scale should be around 1/300
(ignoring ASA) -- but value and scale are returned as VAL_INT

The macros `S626_CLKSRC_COUNTER`, `S626_CLKSRC_TIMER` and
`S626_CLKSRC_EXTENDER` are used logically to set the operating mode of
an encoder channel.  `S626_CLKSRC_COUNTER` (0) is also used as a 2-bit
physical value to set the counter source of an encoder channel to
"encoder".

Rename the macros to `S626_ENCMODE_COUNTER`, `S626_ENCMODE_TIMER` and
`S626_ENCMODE_EXTENDER` and rename some other macros and (unused)
functions relating to the encoder mode for consistency.

Define new macros to specify the physical counter source values for the
'CRA' register and rename the corresponding bitshift and mask macros
accordingly.  The physical values for the counter source are:

  S626_CNTSRC_ENCODER = 0      // encoder
  S626_CNTSRC_DIGIN = 1        // digital inputs
  S626_CNTSRC_SYSCLK = 2       // system clock up
  S626_CNTSRC_SYSCLK_DOWN = 3  // system clock down

Also use the `S626_CNTSRC_SYSCLK` value as a bitmask (bit 1) to indicate
either of the system clock values, with the direction (bit 0) indicated
separately in this case.

When setting up an encoder channel, the setup value includes a polarity
and direction, but these are the same bit of the setup value:

  S626_CLKPOL_POS = S626_CNTDIR_UP = 0

  S626_CLKPOL_NEG = S626_CNTDIR_DOWN = 1

In the construction of the setup value, both the CLKPOL and the CNTDIR
constants are shifted by the same amount `S626_BF_CLKPOL`.  Only the
following combinations are set up currently (this may change if user
configuration of the encoder is implemented properly):

  (S626_CLKPOL_POS << S626_BF_CLKPOL)

  (S626_CLKPOL_POS << S626_BF_CLKPOL) |
  (S626_CNTDIR_UP << S626_BF_CLKPOL)

  (S626_CLKPOL_POS << S626_BF_CLKPOL) |
  (S626_CNTDIR_DOWN << S626_BF_CLKPOL)

The first two are used in "counter" mode and is equivalent to:

  (S626_CLKPOL_POS << S626_BF_CLKPOL)

The last one is used in "timer" mode and is equivalent to:

  (S626_CNTDIR_DOWN << S626_BF_CLKPOL)

Use the shorter equivalents.  The comments in "s626.h" indicate that the
'CLKPOL' constants make more sense for the "counter" mode (when the
encoders operate as up/down counters) and the 'CNTDIR' constants make
more sense for the "timer" mode.
