Nicolas Saenz Julienne 0c51d8f5c8 clk: bcm2835: Do not use prediv with bcm2711's PLLs 
[ Upstream commit f34e4651ce66a754f41203284acf09b28b9dd955 ]

Contrary to previous SoCs, bcm2711 doesn't have a prescaler in the PLL
feedback loop. Bypass it by zeroing fb_prediv_mask when running on
bcm2711.

Note that, since the prediv configuration bits were re-purposed, this
was triggering miscalculations on all clocks hanging from the VPU clock,
notably the aux UART, making its output unintelligible.

Fixes: 42de9ad400af ("clk: bcm2835: Add BCM2711_CLOCK_EMMC2 support")
