Hans de Goede dd242a080d ACPI / LPSS: Only call pwm_add_table() for the first PWM controller 
At least on the UP board SBC both PWMs are enabled leading to us
trying to add the same pwm_lookup twice, which leads to the following:

[    0.902224] list_add double add: new=ffffffffb8efd400,
               prev=ffffffffb8efd400, next=ffffffffb8eeede0.
[    0.912466] ------------[ cut here ]------------
[    0.917624] kernel BUG at lib/list_debug.c:31!
[    0.922588] invalid opcode: 0000 [#1] SMP
...
[    1.027450] Call Trace:
[    1.030185]  pwm_add_table+0x4c/0x90
[    1.034181]  bsw_pwm_setup+0x1a/0x20
[    1.038175]  acpi_lpss_create_device+0xfe/0x420
...

This commit fixes this by only calling pwm_add_table() for the first
PWM controller (which is the one used for the backlight).
