usb: gadget: lpc32xx_udc: Fix compatibility with STOTG04
The STOTG04 is an replacement for ISP1301.
Most of the registers on STOTG04 are the same as on ISP1301, but the
register ISP1301_I2C_OTG_CONTROL_2 (address 0x10) doesn't exist on the
ST part.
This is a work around for this by using the interrupt source register that
should behave the same on both parts and has the needed information.
