Passing an SMBIOS buffer pointer to dell_smbios_send_request() is
redundant as it should always operate on the SMBIOS buffer exported from
the module.

Some laptop models have working hotkeys without the need of the driver
to activate them.
This patch adds a module parameter to tell the driver not to register
the hotkeys.
The new parameter is useful in DE less installations or where the DE
does not handle the hotkeys (see bug 99501).

This patch adds support to query and set the "Cooling Method" feature,

- Maximum Performance

After going through the math and constraints checking to compute load

duty cycle are.

When converting period and duty_cycle from nanoseconds to fclk cycles,
the error introduced by the integer division can be appreciable, especially
in the case of slow fclk or short period. Use DIV_ROUND_CLOSEST_ULL() so
that the error is kept to +/- 0.5 clock cycles.

Add sanity checking to ensure that we do not program load or match values
that are out of range if a user requests period or duty_cycle values which
are not achievable. The match value cannot be less than the load value (but
can be equal), and neither can be 0xffffffff. This means that there must be
at least one fclk cycle between load and match, and another between match
and overflow.

Fix the calculation of load_value and match_value. Currently they
are slightly too low, which produces a noticeably wrong PWM rate with
sufficiently short periods (i.e. when 1/period approaches clk_rate/2).
Example:
clk_rate=32768Hz, period=122070ns, duty_cycle=61035ns (8192Hz/50% PWM)
Correct values: load = 0xfffffffc, match = 0xfffffffd
Current values: load = 0xfffffffa, match = 0xfffffffc
effective PWM: period=183105ns, duty_cycle=91553ns (5461Hz/50% PWM)
