Allow pwm_enable()/pwm_disable() to be called as many times
as the driver wants (and not even count them).
The PWM model is different from things like the clock API
where we need enable counting, because PWMs have one
exclusive user per PWM whereas the clock API can have
multiple users of the same clock.

Without a GPL-compatible license this driver cannot be built as a module,
because the platform_driver_* API is only exported to GPL modules.

Currently PWM0/2 (pxa27x_device_pwm0 at 0x40b00000 and 0x40b00010
are registered as as pwm_id 0 and 1, PWM1/3 (pxa27x_device_pwm1 at
0x40c00000 and 0x40c00010) are registered as pwm_id 2 and 3.
This patch corrects the pwm_ids to match the documented register names.

Patch mainly from Eric Miao, with minor edits by rmk.

Note: PWM0 and PWM2 share the same register I/O space and clock gating
on pxa{27x, 3xx}, thus PWM2 is treated in the driver as a child PWM of
PWM0. And this is also true for PWM1/3.

i2c-core takes care of the possible corruption of 24RF08 chips for

Update all the remaining new-style i2c drivers to use standard module
aliasing instead of the old driver_name/type driver matching scheme.

Note that the tuner driver is a bit quirky at the moment, as it
overwrites i2c_client.name with arbitrary strings. We write "tuner"
back on remove, to make sure that driver cycling will work properly,
but there may still be troublesome corner cases.

There is a strange chip at 0x2e on the second SMBus channel of the
DFI Lanparty NF4 Expert motherboard. Accessing the chip reboots the
system. As there's nothing interesting on this SMBus channel, the
easiest and safest thing to do is to disable it on that board.

done originally:
