The zx296718 clock driver has a creative way of assigning the register
values for each clock, by initializing an __iomem pointer to an
offset and then later adding the base (from ioremap) on top
with a cast to u64. This fail on all 32-bit architectures during
compile testing:
drivers/clk/zte/clk-zx296718.c: In function 'top_clocks_init':
drivers/clk/zte/clk-zx296718.c:554:35: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
zx296718_pll_clk[i].reg_base += (u64)reg_base;
drivers/clk/zte/clk-zx296718.c:579:29: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
drivers/clk/zte/clk-zx296718.c:592:31: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
It would be nice to avoid all the casts, but I decided to simply
shut up the warnings by changing the type from u64 to uintptr_t,
which does the right thing in practice.

The ZX296718 clocks are statically listed and registered. More
clock will be added later.

It adds a clock driver for zx296702 SoC to register the clock tree to
Common Clock Framework. All the clocks of bus topology and some the
peripheral clocks are ready with this commit. Some missing leaf clocks
for peripherals will be added later when needed.
