soc: rockchip: grf: postpone jtag switching for PX30 Soc

Browse Source 
PX30_GRF_SOC_CON5 is intended for postponing the auto switch
of pinmux from SDMMC to JTAG after removing the SD cards.
However, the default value is too small to meet the actual
requirement. Increase this value to 5 seconds currently.
