Introduce pcim_alloc_irq_vectors(), a device-managed version of
pci_alloc_irq_vectors(), In some i2c drivers, If pcim_enable_device()
has been called before, then pci_alloc_irq_vectors() is actually a
device-managed function. It is used as a device-managed function, So
replace it with pcim_alloc_irq_vectors().
Changelog
---------
v4 -> v5:
- Remove the check of enable device in pcim_alloc_irq_vectors()
and make it as a static line function.
- Modify the subject name in patch 3 and patch 4.
v3 -> v4:

v2 -> v3:
- Add some commit comments for replace some codes in
pcim_release() by pci_free_irq_vectors().
- Simplify the error handling path in i2c designware

- Use pci_free_irq_vectors() to replace some code in
pcim_release().
- Modify some commit messages.
