Subject: [PATCH] gpio/langwell: allocate IRQ descriptors dynamically for
 SPARSE_IRQ

Since x86 is using SPARSE_IRQ by default nowadays it means that we need to
allocate IRQ descriptors dynamically using irq_alloc_descs() otherwise the
genirq code fails to convert our irq numbers to suitable descriptors.
