ARM: 7343/1: sa11x0: convert to sparse IRQ

Now that Neponset, UCB1x00 and SA1111 are all converted to use the IRQ
allocation interfaces, we can enable sparse IRQ support for SA11x0
platforms.

 /*
  * Figure out the MAX IRQ number.
  *
- * If we have an SA1111, the max IRQ is S1_BVD1_STSCHG+1.
- * If we have an LoCoMo, the max IRQ is IRQ_BOARD_START + 4
- * Otherwise, we have the standard IRQs only.
+ * Neponset, SA1111 and UCB1x00 are sparse IRQ aware, so can dynamically
+ * allocate their IRQs above NR_IRQS.
+ *
+ * LoCoMo has 4 additional IRQs, but is not sparse IRQ aware, and so has
+ * to be included in the NR_IRQS calculation.
