mmc: sunxi: fix MACH_SUN9I typo in get_mclk_offset()
The get_mclk_offset() function used the non-existent Kconfig symbol
CONFIG_MACH_SUN9I_A80 instead of CONFIG_MACH_SUN9I, causing the
MMC2 clock register to be written at 0x06000090 instead of
0x06000418. This corrupted the CMD2 response and made eMMC
completely unresponsive.
Also the legacy (SPL) sunxi_mmc_init() did not include CONFIG_MACH_SUN9I
in the 8-bit bus width condition, so MMC2 (eMMC) would only use
4-bit mode in the SPL, which is insufficient for reliable boot.
Tested on a Cubieboard4 A80: with both fixes, SPL loads U-Boot proper
and boots Debian 12 from eMMC with no SD card present.
