Change the I2C Slave Address of the PCA9450A:
0x35 --> 0x25
According to the NXP documentation, in the datasheet:
PCA9450DS.pdf (Rev 1.0 - 19 November 2019)
in the table 19 "PCA9450 I2C Slave Address) at page 27/96,
all the PCA9450 have the same I2C address. In particular, in case of 7-bit Slave Address, the address is 0x25.
This modification was tested on the imx8mm-evk, with the SOC equipped with the PCA9450A instead of the previous ROHM BD71847.
