Before this patch,  HVR900/HVR950 were incorreclty going back to analog. The
result is that only digital were working.

This patch provides the proper setup for analog/digital and tuner callback.
It also properly resets analog into a sane state at open().

Now, all registers will follow the same convension:

EM28XX_R<reg_number>_<reg_name>

This allows to associate a register with its value, and also with a canonical
name. Also, registers that are specific to a given chip were renamed accordingly,
as EM2800_foo (for 2800 only registers) or EM2880_foo (for registers that started
to appear on em2880).

Before this patch, registers 0x04 and 0x08 were referenced by its value. This is

em28xx.h contains lots of different stuff inside. The better is to break it on

This is more conservative than just removing the msleep() from
em28xx_write_regs_req(), since some old hardware may still need it.
So, it will remove the sleep time only for those chips where this
removal were tested.
