This patch adds support for Si2147-A30 tuner. Fairly trivial, no firmware needed for this tuner. However, command 14 00 02 07 01 00 seems to be mandatory. On Si2157 and Si2158 the value 0x0100 is the default value, so this patch does not impact the existing tuners/devices. On Si2147 the default is 0x0000 and I can't get a lock with that value.
While here, fix the return length of the previous set command to 4 bytes.

Add a variable into state to keep track if firmware has been loaded or not.
Skip firmware loading in case it is already loaded (resume from sleep).

Instead of sending command 13 to the tuner, send command 16 when sleeping. This
behaviour is observed when using manufacturer provided binary-only Linux driver
for TechnoTrend CT2-4400 (Windows driver does not do power management).
The issue with command 13 is that firmware loading is necessary after that.
This is not an issue with tuners that do not require firmware, but starting
streaming after sleep on an Si2158 takes noticeable time as firmware is
loaded on resume.

Same thing for si2157 as Antti did earlier for tda18212:
There is no need to print module name nor function name as those
are done by kernel logging system when dev_xxx logging is used and
driver is proper I2C driver.
While here, fix a typo ("unknown") in si2157_init.

The struct prototype is defined at the beginning of the code as
"si2157_ops" but the real struct is called "si2157_tuner_ops".
This is causing the name to be empty on this info msg: si2157 16-0060:
si2157: found a '' in cold state
