vexpress: Initialise the sysregs before setting up the clocks

Following arm64 commit bc3ee18 (arm64: init: Move of_clk_init to time_init()), vexpress_osc_of_setup() is called via of_clk_init() long before initcalls are issued. Initialising the vexpress oscillators requires the vespress sysregs to be already initialised, so this patch adds an explicit call to vexpress_sysreg_of_early_init() in vexpress oscillator setup function.
