arm64: dts: imx8mp-venice-gw74xx: fix TPM SPI frequency

Browse Source 
commit 0bdaca0922175478ddeadf8e515faa5269f6fae6 upstream.

The IMX8MPDS Table 37 [1] shows that the max SPI master read frequency
depends on the pins the interface is muxed behind with ECSPI2
muxed behind ECSPI2 supporting up to 25MHz.

Adjust the spi-max-frequency based on these findings.
