Add non-DT IOMUX definitions for the i.MX50 SOC by converting linux
dts/imx50-pinfunc.h by script.
perl -we 'while(<>) {
 next unless /^#define MX50_PAD/;
 @in=split "[[:space:]]+", uc($_);
 @out=();
 @out[0..4]=@in[3, 2, 5, 4, 6];
 $out[2] =~ s/0X//;
 $out[4] =~ s/0X//;
 $out[3] = "__NA_" if $out[3] eq "0X000";
 push @out, $in[1] =~ /__UART/? "MX50_UART_PAD_CTRL": "NO_PAD_CTRL";
 $out=join(", ", @out);
 $out =~ s/0X/0x/g;
 print "#define $in[1]\t\t\tIOMUX_PAD($out)\n";
}' < dts/src/arm/imx50-pinfunc.h

Additional changes:
* typical PAD settings for UART, SPI, I2C and ESDHC
* SION bits set for all I2C MUX options
