This patch removes the IRQ mask initialization which is already done some lines
above.
This was actually a bug: The init was supposed to set the bits for the
(chained) SUB IRQs. But this is already fixed by the previous patch, doing this
implicitely via irq_set_chained_handler().

This patch fixes the issue of an access to a yet uninitialized data structure
at the point where irq_set_chained_handler() was called by moving the
respective calls to the end of lpc32xx_init_irq().
The call path was:
irq_set_chained_handler()
-> __irq_set_handler()
-> irq_startup()
-> irq_enable()
-> desc->irq_data.chip->irq_unmask()
at which point lpc32xx_unmask_irq() effectively read desc->irq_data.hwirq which
was only later initialized.

This patch removes the call to irq_alloc_descs() which always returns an error
since the descriptors are always preallocated already.

irq.c uses handle_level_irq() as the unconditional default handler. This patch
uses handle_edge_irq() instead for edge type irqs.

This patch adds ethernet support to the LPC32xx ARM architecture. The actual

This patch fixes the initialization of the interrupt controller of the LPC32xx
by correctly setting up SIC1 and SIC2 instead of (wrongly) using the same value
as for the Main Interrupt Controller (MIC).

The GPI_28 IRQ was not registered properly. The registration of
IRQ_LPC32XX_GPI_28 was added and the (wrong) IRQ_LPC32XX_GPI_11 at
LPC32XX_SIC1_IRQ(4) was replaced by IRQ_LPC32XX_GPI_28 (see manual of
LPC32xx / interrupt controller).
