phy: phy-mtk-dp: Fix pdata array members initialized as pointers

Building arm/arm64/i386 allmodconfig with clang fails:

  drivers/phy/mediatek/phy-mtk-dp.c:761:18: error: incompatible pointer
  to integer conversion initializing 'u16' (aka 'unsigned short') with
  an expression of type 'const u16[4]' [-Wint-conversion]
  drivers/phy/mediatek/phy-mtk-dp.c:761:18: error: initializer element
  is not a compile-time constant
  drivers/phy/mediatek/phy-mtk-dp.c:761:18: error: suggest braces around
  initialization of subobject [-Werror,-Wmissing-braces]

14 errors in total, one set per offending member.

off_ana_lane, off_dig_lane and driving_params are declared as arrays in
struct mtk_dp_phy_pdata:

	u16 off_ana_lane[MTK_DP_PHY_MAX_LANES];
	u16 off_dig_lane[MTK_DP_PHY_MAX_LANES];
	u32 driving_params[PHYD_DIG_NUM_DRV_PARA_REGS];

but the SoC data instances initialize them with compound literals. A
compound literal is an object, not an initializer list, so this is not
an array initializer: the member is initialized element-wise from a
scalar, the first element gets the address of the literal truncated to
u16/u32, and the remaining elements are zeroed. Hence the three
diagnostics above - the pointer-to-integer conversion, the address not
being a compile-time constant, and the missing braces.

Arrays are the right type here, since both members are indexed per lane
and driving_params is sized with ARRAY_SIZE(), so drop the casts and use
plain braced initializers.

Found by KernelCI builds of the linus-next tree.
