The value of the 'pll_type' field of 'struct apps_pll_data'
is used only by the probe function to decide which config
function should be called for the actual PLL. However this
can be derived also from the 'pll' field  which makes the
'pll_type' field redundant.

Additionally, the CLK_ALPHA_PLL_TYPE_* enumeration values
are meant to be used as indices to the 'clk_alpha_pll_regs'
array so using those to define the pll type in this driver
is misleading anyway.

Change the probe function to use the 'pll' field to determine
the configuration function to be used, and remove the
'pll_type' field to simplify the code.

No functional changes.
