From 'clock-frequency' device tree property, configure I2C SCL
frequency by calculating the timing register values according to
input clock.

After soft reset in reinit function, the timing registers are set
to default values (configured in vivado design). So, setting SCL
frequency is done inside reinit function after the soft reset.
This allows configuration of SCL frequency exclusively through
software via device tree property, overriding the vivado design.
If the clock-frequency parameter is not specified in DT, driver
doesn't configure frequency, making it backward compatible.

Because of commit 43f33b6 ("hwmon: (pmbus) Add 'phase' parameter
where needed for multi-phase support"), the function "pmbus_read_word_data"
needs one more argument "phase". Since tps544 doesn't support
multi-phase, this "phase" argument will be ignored. Let's pass "0xff"
to pmbus_read_word_data just to avoid compile error.

Because of commit dd43193 ("hwmon (pmbus) use simple i2c probe
function"), remove "id" argument from tps544_probe since pmbus_do_probe
doesn't need it anymore.

The Xen pvcalls frontend driver needs to be explicitly enabled, and
there isn't a way to do it upstream yet. This patch adds a simple
boolean command line option (gated on CONFIG_XEN_PVCALLS_FRONTEND) to
enable pvcalls. It is a temporary solution but it is the best we can do
until a proper upstream mechanism to enable pvcalls is introduced.

The patch has no effect if CONFIG_XEN_PVCALLS_FRONTEND is not enabled,
or if pvcalls=true is not passed as a command line argument.
