cpu/nrf52: spi_twi_irq add workaround for nRF52810 vendor file

Browse Source 
Either nRF52810 should define SPIM_COUNT 2 or nRF52805 should
define SPIM_COUNT 1.
But as it nRF52805 defines SPIM_COUNT 2 and nRF52810 defines SPIM_COUNT 1
even though both have a single SPI and a single, separate TWI peripheral.

Re-define SPIM_COUNT to 2 on nRF52810 as this is the easiest solution.

/**
* The vendor file is weird here. nRF52805 is the only other MCU
* that has only 1 SPI and separate 1 TWI interface, but define
* SPIM_COUNT = 2, which is in line with how it is used here.
* nRF52810 has the same set of SPI/TWI peripherals, but defines
* SPIM_COUNT = 1 which is more logical.
* Just re-define it to work around this inconsistency.
