Subject: [PATCH] arm64: dts: zynqmp: Add compatible strings for si5328

From: Quanyang Wang <quanyang.wang@...driver.com>

The function of_i2c_get_board_info will call of_modalias_node to check
if a device_node contains "compatible" string. So let's assign the
proper string "silabs,si5328" to clock-generator@...s compatible
property to eliminate the error info as below:

i2c i2c-10: of_i2c: modalias failure on /axi/i2c@...30000/i2c-mux@...i2c@...lock-generator@69
i2c i2c-10: Failed to create I2C device for /axi/i2c@...30000/i2c-mux@...i2c@...lock-generator@69

Fixes: 82a7ebf00224 ("arm64: dts: zynqmp: Add DT description for si5328 for zcu102/zcu106")
