In order to be able to unify 64 and 32 bit implementations of
wr_reg64, let's convert it to use helpers from
<linux/io-64-nonatomic-hi-lo.h> first. Here are the steps of the
transformation:

1. Inline wr_reg32 helpers:

	if (!caam_imx && caam_little_end) {
		if (caam_little_end) {
			iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
			iowrite32(data, (u32 __iomem *)(reg));
		} else {
			iowrite32be(data >> 32, (u32 __iomem *)(reg) + 1);
			iowrite32be(data, (u32 __iomem *)(reg));
		}
	} else {
		if (caam_little_end) {
			iowrite32(data >> 32, (u32 __iomem *)(reg));
			iowrite32(data, (u32 __iomem *)(reg) + 1);
		} else {
			iowrite32be(data >> 32, (u32 __iomem *)(reg));
			iowrite32be(data, (u32 __iomem *)(reg) + 1);
		}
	}

2. Transfrom the conditionals such that the check for
'caam_little_end' is at the top level:

	if (caam_little_end) {
		if (!caam_imx) {
			iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
			iowrite32(data, (u32 __iomem *)(reg));
		} else {
			iowrite32(data >> 32, (u32 __iomem *)(reg));
			iowrite32(data, (u32 __iomem *)(reg) + 1);
		}
	} else {
		iowrite32be(data >> 32, (u32 __iomem *)(reg));
		iowrite32be(data, (u32 __iomem *)(reg) + 1);
	}

3. Invert the check for !caam_imx:

	if (caam_little_end) {
		if (caam_imx) {
			iowrite32(data >> 32, (u32 __iomem *)(reg));
			iowrite32(data, (u32 __iomem *)(reg) + 1);
		} else {
			iowrite32(data >> 32, (u32 __iomem *)(reg) + 1);
			iowrite32(data, (u32 __iomem *)(reg));
		}
	} else {
		iowrite32be(data >> 32, (u32 __iomem *)(reg));
		iowrite32be(data, (u32 __iomem *)(reg) + 1);
	}

4. Make use of iowrite64* helpers from <linux/io-64-nonatomic-hi-lo.h>

	if (caam_little_end) {
		if (caam_imx) {
			iowrite32(data >> 32, (u32 __iomem *)(reg));
			iowrite32(data, (u32 __iomem *)(reg) + 1);
		} else {
			iowrite64(data, reg);
		}
	} else {
		iowrite64be(data, reg);
	}

No functional change intended.
