Generated nrf52.go is missing IRQ_SPIM1_SPIS1_TWIM1_TWIS1_SPI1_TWI1

While trying (and so far failing) to get the I2C interface working on the pca10040 I noticed that there is a missing interrupt value.

const (
	IRQ_POWER_CLOCK                       = 0  // Power control // Clock control
	IRQ_RADIO                             = 1  // 2.4 GHz Radio
	IRQ_UARTE0_UART0                      = 2  // UART with EasyDMA // Universal Asynchronous Receiver/Transmitter
	IRQ_SPIM0_SPIS0_TWIM0_TWIS0_SPI0_TWI0 = 3  // Serial Peripheral Interface Master with EasyDMA 0 // SPI Slave 0 // I2C compatible Two-Wire Master Interface with EasyDMA 0 // I2C compatible Two-Wire Slave Interface with EasyDMA 0 // Serial Peripheral Interface 0 // I2C compatible Two-Wire Interface 0
	IRQ_NFCT                              = 5  // NFC-A compatible radio
	IRQ_GPIOTE                            = 6  // GPIO Tasks and Events
...

Notice that IRQ 4 is missing. It is supposed to be
IRQ_SPIM1_SPIS1_TWIM1_TWIS1_SPI1_TWI1 = 4 according to the nrf52.svd file:

    <peripheral derivedFrom="TWIM0">
      <name>TWIM1</name>
      <description>I2C compatible Two-Wire Master Interface with EasyDMA 1</description>
      <baseAddress>0x40004000</baseAddress>
      <alternatePeripheral>SPIM1</alternatePeripheral>
      <interrupt>
        <name>SPIM1_SPIS1_TWIM1_TWIS1_SPI1_TWI1</name>
        <value>4</value>
      </interrupt>
    </peripheral>

This value is of course also missing from the generated nrf52.s file.

I was missing a few interrupts for derived peripherals. Fixed in b36b9c2.
