Add stub functions for timer and dev_trans_start

mdio45_probe calls the read callback multiple times. So handle it inside the
LCD.

Add the following functions
* __hw_addr_sync_dev
* __hw_addr_unsync_dev
* pci_disable_msix
* pci_enable_msix_range
* netif_tx_wake_all_queues

pci helpers are required for manipulating msi interrupts. __hw_addr helpers
provide functionality for adding/removing hw address to the netdev address
lists.

Also add print and dump stack in all the stub functions to know where this
function originates from.

In the native kernel, usleep_range leans on the hrtimer interface. As we don't
have any timer support inside LCDs, make this api perform an udelay instead.
Both usleep_range and msleep needs to be fixed in the future

As dma support is added to liblcd, remove the old stubs

Some options are not supported by the LCD driver as of now, such as IOV, DMA,
DCA, DCB. #ifdef all those functions.

msleep is just a wrapper around udelay, which is a tight loop. msleep must be
replaced with a real timer in the future

Replace
* dev_{warn,err,info,crit} with LIBLCD variants.
* v{m,z}alloc with kmalloc for now as vmalloc is not fully supported in the liblcd
implementation.
* {alloc,free}_pages with lcd variants

Mask functions that won't be used with LCD driver (for instance irq related
stuff). Add stubs for other functions that are unlikely to be RPC-ed or pulled
in.
