lantiq: Fix an sleeping function called from invalid context
...
The ifx_pcie_bus_enum_hack() function is called in
ifx_pcie_read_config() while holding the ifx_pcie_lock spinlock. The
ifx_pcie_bus_enum_hack() function calls pci_get_slot() which could
sleep. Add a new function for pci_get_slot() which does not use a
semaphore, the mutex should be sufficient. This fixes the sleep in
atomic context which could cause a hang of the system.
This fixes the following warning seen with
CONFIG_KERNEL_DEBUG_ATOMIC_SLEEP=y.
