uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead

https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      Dap is a small statistics and graphics package based on C. Version 3.0 and
+      later of Dap can read SBS programs (based on the utterly famous, industry
+      standard statistics system with similar initials - you know the one I
+      mean)! The user wishing to perform basic statistical analyses is now freed
+      from learning and using C syntax for straightforward tasks, while
+      retaining access to the C-style graphics and statistics features provided
+      by the original implementation. Dap provides core methods of data
+      management, analysis, and graphics that are commonly used in statistical
+      consulting practice (univariate statistics, correlations and regression,
+      ANOVA, categorical data analysis, logistic regression, and nonparametric
+      analyses).
