Instead, pass the sideband data specified by the driver.
- Fix the driver's callback signatures: a. Add an unused pointer to void
for table matchers (currently only clocksource callback) b. Change
the type of sideband data to kernel_ulong_t.

We have multiple "earlycon" early_param handlers - merge the DT one into
the main earlycon one. This means the earlycon early_param handler does
not just return success if no options are specified.
