Clean up i2c-amd-mp2-{pci,plat} drivers:
* Use pci_* logging functions provided by the kernel's PCI API.
* Remove unused macros.
* Remove useless __func__ from logging.

Changes since v1:
* Remove useless __func__ from logging.
* Assign pci_dev to local variable where applicable.

Changes since v2:
* Remove duplicate local pointer to pci_dev.

  i2c: i2c-amd-mp2: Remove unused macro

Use pci_{info,warn,err,dbg} functions of the kernel's PCI API.
Remove unnecessary ndev_pdev(), ndev_name() and ndev_dev() macros.
While at it, remove useless __func__ from logging.

I haven't given you the tag for this patch, but this time it's okay,
no need to resend.

$subject looked wrong to me so I changed it to "convert to PCI logging
functions". Applied to for-next, thanks!
