[PATCH] ARM: dts: ti/omap: dra7: Fix PCIe PHY divided clock generation

[Danny Baumann]

From: Danny Baumann <danny.baumann@legrand.com>

Commit d0bdd8bb7f35a2b4434a3ef665f9cfc3aba886c7 ("ARM: dts: ti/omap:
dra7: fix redundant clock divider definition") removed the ti,dividers
property in favor of the ti,max-div property. That particular divider is
'backwards', though (0 = 'divide by 2', 1 = 'do not divide, see AM574x
TRM, table 3-846 on page 939), so the removal of that property inverted
the driver behavior.
Restore previous behavior by restoring the ti,dividers property and fix
the redundancy by removing the ti,max-div property instead.
