armv7: replace read/write macros with inlines

This enables type checking for safety as to help prevent errors like
    http://review.coreboot.org/#/c/3038/ . Now compilation fails if the
    wrong type is passed into readb/readw/readl/writeb/writew/writel
    or other macros in io.h.

This also deprecates readw/writew. The previous definition was 16-bits
    which is incorrect since wordsize on ARMv7 is 32-bits and there was
    only 1 instance of writew (#if 0'd anyway). Going forward we should
    always use read{8,16,32} and write{8,16,32} where N specifies the
    exact length rather than relying on ambiguous definition of wordsize.

Since many macros relied on __raw_*, which were basically the same
    (minus data memory barrier instructions), this patch also gets rid
    of __raw_*. There were parts of the code which ended up using these
    macros consecutively, for example:
    	setbits_le32(&regs->ch_cfg, SPI_CH_RST);
    	clrbits_le32(&regs->ch_cfg, SPI_CH_RST);

In such cases the safe versions of readl() and writel() should be
    used anyway.

Note: This also fixes two dubious casts as to avoid breaking
    compilation.
