mcu/lpc55: Enable MPU for USB_SRAM access
USB_SRAM by default requires aligned access as it is mapped same way peripherals are accessed. To overcome this limitation (needed by TinyUSB) MPU has to be enabled that configures USB_SRAM so there is no alignment limitations. Without this TinyUSB implementation will not work.
