Convert the Hisilicon Bootwrapper boot method binding to DT schema format
using json-schema.

The property boot-method contains two groups of physical address range
information: bootwrapper and relocation. The "uint32-array" type is not
suitable for it, because the field "address" and "size" may occupy one or
two cells respectively. Use "minItems: 1" and "maxItems: 2" to allow it
can be written in "<addr size addr size>" or "<addr size>, <addr size>"
format.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW  = 1 = IRQ_TYPE_EDGE_RISING

Correct the interrupt flags, assuming the author of the code wanted some
logical behavior behind the name "ACTIVE_xxx", this is:
  ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW
