Krzysztof Kozlowski 1e0228fd20 hw/arm/exynos: Fix Linux kernel division by zero for PLLs
Without any clock controller, the Linux kernel was hitting division by
zero during boot or with clk_summary:
[    0.000000] [<c031054c>] (unwind_backtrace) from [<c030ba6c>] (show_stack+0x10/0x14)

[    0.000000] [<c05b2660>] (dump_stack) from [<c05b11a4>] (Ldiv0+0x8/0x10)

[    0.000000] [<c125d7e8>] (exynos4_clk_init) from [<c12335f4>] (of_clk_init+0x17c/0x210)
[    0.000000] [<c12335f4>] (of_clk_init) from [<c1204700>] (time_init+0x24/0x2c)
[    0.000000] [<c1204700>] (time_init) from [<c1200b2c>] (start_kernel+0x24c/0x38c)
[    0.000000] [<c1200b2c>] (start_kernel) from [<4020807c>] (0x4020807c)

Provide stub for clock controller returning reset values for PLLs.
