rtw_startbss_cmd can return the result of calling rtw_enqueue_cmd, which
can return the result of calling _rtw_enqueue_cmd, but they all have
different return types (u8, u32, and sint, respectively).
As all of these functions return error codes, change all the return types
to int, in preparation for converting these functions to use standard
kernel error codes.
Also, remove extern from the function declaration to maintain Linux kernel

The `insn_read` handler for the EEPROM subdevice on M-series boards
(`ni_m_series_eeprom_insn_read()`) currently ignores `insn->n` (the
number of samples to read) and assumes a single sample is to be read
into `data[0]`. Fortunately, the Comedi core ensures that `data[]` has
a length of at least 16 so there is no problem with array bounds.
The usual Comedi convention for `insn_read` handlers is to read the same
channel `insn->n` times into successive elements of `data[]` so let's do
that. (Each channel corresponds to a single EEPROM address.) In this
case, the data value comes from a local copy of the EEPROM contents.
Also, follow the usual Comedi convention and return `insn->n` from the
handler to indicate success (although any non-negative value will do).

Since we do not expect the EEPROM data at a particular address to change
between readings, let's just read it once and copy the value `insn->n`
times.

The `insn_write` handler for the calibration subdevice
(`ni_calib_insn_write()`) currently ignores `insn->n` (the number of
samples to write) and assumes a single sample is to be written, but
`insn->n` could be 0, meaning no samples should be written, in which
case `data[0]` is invalid.
Change `ni_calib_insn_write()` to only write to the calibration device
if `insn->n > 0`. There isn't much point writing all the values when
`insn->n > 1`, so just write the last one (`data[insn->n - 1]`).
Also follow the usual Comedi convention and return `insn->n` from the
handler to indicate success (although any non-negative return value will
do as far as the Comedi core is concerned).

The driver previously grabbed the SD pins for itself, ignoring the pin
controller. Remove this, and allow the pinctrl subsystem to set up the
pins using the device tree mappings. This allows this driver to work on
related devices that have a different pin controller mapping, such as
the MT7688. The hardcoded bit index was incorrect on that device.
The driver now needs a pin controller reference in its device tree node:
sdhci: /* ... */ {
compatible = "ralink,mt7620-sdhci";
pinctrl-names = "default";
pinctrl-0 = <&sdhci_pins>;
// ...
};
This change could break SD controller functionality on existing devices
whose device trees do not specify a pin controller and state for the SD
node.
