[PATCH] pci: pwrctl: fix the kerneldoc tag for private fields

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

The correct tag for marking private fields in kerneldoc is "private:",
not capitalized "Private:". Fix the pwrctl struct to silence the
following warnings:

  Warning: include/linux/pci-pwrctrl.h:45 struct member 'nb' not described in 'pci_pwrctrl'
  Warning: include/linux/pci-pwrctrl.h:45 struct member 'link' not described in 'pci_pwrctrl'
  Warning: include/linux/pci-pwrctrl.h:45 struct member 'work' not described in 'pci_pwrctrl'

Fixes: 4565d2652a37 ("PCI/pwrctl: Add PCI power control core code")
