qcom_geni_i2c_conf() writes a hardcoded 0 to SE_GENI_CLK_SEL, which
selects an index from the hardware clock performance table. This always
picks the first table entry regardless of the actual source clock
configuration. On platforms where the matching entry is not at index 0,
the wrong source clock divider is active and the I2C bus runs at an
incorrect frequency.
Use geni_se_clk_freq_match() in geni_i2c_clk_map_idx() to find the
performance table index for the source clock (32 MHz or 19.2 MHz). Store
the resolved index in a new clk_idx field in geni_i2c_dev and write it
to SE_GENI_CLK_SEL instead of the hardcoded 0.
