Hopefully this isn't too late for 3.12.

In commit 7dc19d5a (convert shrinkers to new count/scan API)
the return value to PURGE_ALL_CACHES was dropped, causing -EPERM
to always be returned.

This patch re-adds the ret assignment, setting it to the the
ashmem_shrink_count(), which is the lru_count.

(Sorry this was missed in the review!)

The counter 'A' clock polarity field in the 'CRA' register is only 1 bit
wide, but the `S626_CRAMSK_CLKPOL_A` macro shows it as 2 bits wide,
which would overlap with the counter 'A' interrupt source field.  This
is harmless as the macro isn't actually used yet, but correct it anyway
as I want to use it!

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.

The `unsigned char chan_is_bipolar[]` member of `struct rtd_private` is
used with some macros as a packed array of 1-bit values that indicate
whether the corresponding entries in the hardware's "channel-gain" table
have been set to a bipolar (1) or unipolar (0) range, as the raw samples
from the hardware need to be cooked differently in each case.

Replace the declaration of the member with a standard Linux bitfield

access the bitfield with the standard Linux non-atomic bitop functions,
`__set_bit()`, `__clear_bit()` and `test_bit()`.
